Before this change all file-system SecurityExceptions had the same generic form with no indication of *why* the access was blocked. This made debugging and policy development extremely difficult. Two new message keys are introduced: - security.advice.denial.reason.no.allowlist → no allow rule at all - security.advice.denial.reason.not.in.allowlist → path outside allowlist A buildDenialReason(String[] allowedPaths) helper is added to both JavaInstrumentationAdviceAbstractToolbox (for Byte Buddy mode) and JavaAspectJAbstractAdviceDefinitions (for AspectJ mode). The three SecurityException throw-sites in each file-system toolbox now append the reason after a ' | ' separator, e.g.: ... tried to illegally read File /path/secret.txt via Files.readString | Reason: No allow rule configured for this resource type. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Extend the file-system denial-reason suffix to the network, command and thread subsystems, in both the Byte Buddy instrumentation and the AspectJ back-ends. Each subsystem derives its own "no allow rule configured" flag from its allow-lists and appends " | " + buildDenialReason(...) at every SecurityException throw-site. buildDenialReason now takes a boolean. Tests: - End-to-end NOT_PERMITTED coverage (DenialReasonAccessTest) for file, command and thread across all four ArchUnit/WALA x AspectJ/Instrumentation runners, and for network on the AspectJ runners (new SocketConnectMain subject plus two PolicyOneNetworkConnectionAllowed policies). - Toolbox-level NO_ALLOWLIST and NOT_PERMITTED coverage for command, thread and file; the network toolbox already covered both. The NO_ALLOWLIST reason is asserted only at toolbox level, because with an empty policy the static architecture layer (ArchUnit/WALA) blocks the capability before the runtime AOP layer adds the reason. Network is tested end-to-end under AspectJ only, since the instrumentation path does not intercept java.net.Socket connections.
The top-level ares/ directory was a stray, partial copy of source files already under src/main/java/de/tum/cit/ase/ares. It was never part of the Maven build (only src/main/java and src/test/java are compiled), nothing referenced it, and several of its files carried invalid "package .ares..." declarations that could not compile. Its non-corrupted files were exact duplicates of their real counterparts, so nothing unique is lost.
…hitecture analysis getJavaClasses now skips classes whose path contains /ares/api/ via an import filter, so Ares's own infrastructure (reflection, class loading, System.getProperty) is not flagged by the architecture rules. Student attack subjects under /ares/integration/ remain in scope.
…ssing keys Replace the bare combining-diaeresis escape that corrupted 'zurueck' in dynamics.method.return, and add the nine keys present in the English bundle but missing from German (file.tools.*, the new security.architecture.* categories, security.instrumentation.field.not.found), restoring de/en key-set parity.
…M module-access args Add timeout-minutes to build-and-test so the suite fails fast with a readable log instead of the runner losing communication after ~1h; add forkedProcessTimeoutInSeconds and -Xmx to surefire; carry the JVM --add-opens/--add-exports args the AOP advice needs.
Remove the @Userbased integration.FileSystemAccessTest, its FileSystemAccessUser, and the monolithic FileSystemAccessPenguin subject whose whole-class architecture scan cross-contaminated unrelated read tests. These scenarios are covered by the per-method aop.allowed and architecture.forbidden suites. Drop the three now-orphaned root policy files used only by the removed suite.
…ead/overwrite policies Add de.tum.cit.ase.ares.integration.aop.allowed.FileSystemAccessTest to theFollowingClassesAreTestClasses across the read and overwrite policy matrices, so the harness's fixture setup writes are not policed as student code. Without this, allowed read/overwrite operations were wrongly blocked.
JavaArchitectureTestCaseSupportedTest expects the six static cases getStatic now returns; SecurityPolicyJavaDirectorTest expects the default builder for a null policy rather than an NPE; JavaCreatorTest expects the lazily-supplied call graph (no eager getCallGraph); WalaRuleTest expects ArchUnit source-form signatures and that paths through project test helpers fire.
…eadTest assertions Add @uselocale("en") to the aop SystemAccessTest base classes, aop.allowed.FileSystemAccessTest, and ThreadTest so they run under English (matching CI). Update ThreadTest.assertThreadErrorMessage to match the current Ares message ('Ares Security Error', ThreadPenguin, 'create Thread', 'blocked by Ares') instead of obsolete substrings.
… to @Policy The @WhitelistPath/@AddTrustedPackage/@WhitelistClass annotations no longer affect AOP enforcement. Replace them with @Policy(activated=false): StructuralUser (incl. nested InvalidConfigurations) exercises ClassNameScanner correctness, and TrustedClassesUser exercised a removed trust feature, so neither needs runtime enforcement active.
…VM server Per AGENTS.md, a sandboxed test JVM must not start its own server. connectLocallyAllowed targets the external echo server on the loopback and skips when it is absent; an Ares block of an explicitly allowed connection remains a real failure.
…reation subjects Remove the try/catch that wrapped forbidden thread-creation calls in RuntimeException, so the Ares SecurityException reaches the test directly as expected.
Add trusteddir/trusted.txt (aop.allowed) and nottrusteddir/nottrusted.txt (aop.forbidden) fixtures for the file-system delete tests.
Document that sandboxed test JVMs must use an external echo server rather than spinning up an in-process server, and that an Ares block of an explicitly allowed connection is always a real failure.
The previous topical commits were made without a clean 'mvn spotless:apply' pass, so 'mvn spotless:check' (the first CI step) failed on these files. These are pure formatting changes (indentation and line wrapping); no behaviour is affected.
The legacy Ares 1 annotations (@WhitelistPath, @blacklistpath, @AllowThreads, @AllowLocalPort, @TrustedThreads, @WhitelistClass/@WhitelistPackage, @BlacklistPackage, @AddTrustedPackage) are inert under the Ares 2 enforcement path: only @Policy drives the architecture and AOP analysis. Remove every such usage from the integration test users and replace it with an active @Policy that captures the former intent, scanned against the benign HelloWorld subject. The annotation definitions themselves and the AresSecurityConfiguration unit test that exercises them are intentionally left untouched.
…ed calls - Bind java.awt.Desktop interception to the file-read check only (previously bound to read, overwrite, execute and delete simultaneously, so the reported verb was nondeterministic across AspectJ and instrumentation). Applied symmetrically in both enforcement layers. - Remove java.net.URL.openStream from the network-connect map so a content read via ClassLoader.getResourceAsStream is classified as a file read, not a network connection (openConnection stays in the network map). - Remove java.net.URI.create and the pure-parsing URI constructors from the ArchUnit network method list; URI parsing performs no network access. - Exempt JDK-internal reads under java.home (e.g. JceSecurity reading the crypto jurisdiction-policy files) from the file-system checks, mirroring the existing native-library-load exemption, in both layers. - Update the AspectJ copy-config placeholder count to match the edited advice source so the precompile flow stays consistent.
…ityException When the static initialiser's disk-cache read runs inside an active Ares policy boundary, the read (and even the isRegularFile probe, which sat outside the try) is intercepted and throws a SecurityException. That escaped the initialiser as an ExceptionInInitializerError, poisoning JavaWalaTestCase with NoClassDefFoundError for the whole JVM and breaking every subsequent WALA test in the run. Wrap the entire best-effort load in the try and add SecurityException to the multicatch (load and save); on any failure the in-memory cache simply starts empty and outcomes are rebuilt.
…sertions - Fix stale within-path constants in the read tests (the subjects live under read/oldMethods/...), so ArchUnit imports the subject classes and flags the forbidden access. - Add a 3-arg assertAresSecurityExceptionDelete overload and point the WALA delete assertions at the subject's actual deleted path (delete/nottrusteddir/nottrusted.txt); two of them wrongly asserted 'read'. - Point the third-party overwrite assertions at the penguin's actual path and align the lone inconsistent BufferedWriter assertion with its siblings. These classes pass in isolation (200 run, 0 failures); some still fail in the full single-JVM run due to a separate WALA cross-test contamination issue tracked separately.
PrecompileTest invoked writeTestCases(Path.of("")), emitting the generated
architecture/AOP scaffold, localisation resources and Phobos files into the
repository working directory on every run. Write into a JUnit @tempdir instead,
nested deeply enough that the localisation sibling-resources folder and the
Phobos parent climbs both resolve inside the temp directory, which is removed
automatically. Add a .gitignore safety net for the generated paths.

Pull request overview
This PR is a broad stabilization effort for Ares 2’s Maven CI and (currently still-red) test suite, combining production fixes in AOP/instrumentation + architecture enforcement with a large migration/realignment of integration tests and @Policy YAML fixtures.
Changes:
- Stabilize Maven CI/build gates (Spotless, timeouts, JVM/module-access args) to reduce flakiness and hard failures.
- Fix/adjust production enforcement behavior (AOP + instrumentation toolboxes, WALA cache resilience, network/FS classification, improved SecurityException denial reasons + i18n).
- Migrate and realign integration tests/fixtures/policies to active
@PolicyYAMLs (including external echo-server network testing and updated FS delete fixtures).

64-94:⚠️ Potential issue | 🔴 Critical | 🏗️ Heavy liftRemove internal server creation from sandboxed tests.
The three server test methods (
serverAllowedAndAccept,serverAllowedAndTimeout,serverNotAllowed) violate the coding guideline by spinning up internal servers within the sandboxed test JVM viaNetworkPenguin.tryStartServer(). The guideline explicitly forbids this pattern because the server itself becomes subject to the security policy being tested, creating circular dependencies and in-JVM lifecycle flakiness.The
serverAllowedAndAccepttest is particularly problematic: it creates a server (line 68) and then connects to it (line 76), exactly the self-hosted listener pattern the guideline prohibits.Test fixtures must live outside the security boundary. Consider removing these server tests entirely or restructuring them to use an external test service similar to the echo server approach in
connectLocallyAllowed.As per coding guidelines: "In sandboxed test JVMs, never spin up an internal server (echo server, socket listener) to test incoming or outgoing connections. Test fixtures must live outside the security boundary being tested."

In
`@src/main/java/de/tum/cit/ase/ares/api/aop/java/aspectj/adviceandpointcut/JavaAspectJFileSystemAdviceDefinitions.aj`:
- Around line 109-127: isExemptSystemFileAccess currently exempts any "read"
under java.home, which lets student code read arbitrary JDK files; update the
helper (method isExemptSystemFileAccess and any call sites like the AspectJ
pointcut at lines referenced) to stop blanket-allowing reads: either require an
explicit internal-origin signal/flag passed into isExemptSystemFileAccess (or
set by the JVM-internal call path) before returning true for "read", or narrow
the allowed read paths to a tight allowlist of specific JVM-only
files/directories (e.g. specific conf/security or native/lib paths) and only
return true when path matches those exact allowed subpaths; also ensure
NATIVE_LIBRARY_SUFFIXES handling remains unchanged for "execute".
In
`@src/main/java/de/tum/cit/ase/ares/api/aop/java/instrumentation/pointcut/JavaInstrumentationPointcutDefinitions.java`:
- Around line 597-598: The URL.openStream method is wrongly classified as a
file-read; remove "openStream" from the methodsWhichCanReadFiles map (where it's
currently listed) and add it to the methodsWhichCanConnectToNetwork entry for
"java.net.URL" (so the map entry with Map.entry("java.net.URL", List.of(...))
includes "openStream"). This ensures URL.fetches use the network connect/receive
pointcuts (so they are handled by the network advice instead of
JavaInstrumentationReadPath*Advice /
JavaInstrumentationAdviceFileSystemToolbox.checkFileSystemInteraction).
- Around line 474-481: The instrumented handling for java.awt.Desktop is wrong:
remove or relocate "java.awt.Desktop" (and its methods
open/edit/print/browse/browseFileDirectory) out of methodsWhichCanReadFiles and
place it into the correct action/bucket (or add a dedicated Desktop bucket) in
JavaInstrumentationPointcutDefinitions.methodsWhichCanReadFiles/methodsWhichCanExecuteFiles,
and then update JavaInstrumentationAdviceFileSystemToolbox.variableToPath to
explicitly handle non-file URIs/URLs (or make it return a sentinel that causes
checkIfPathIsForbidden to treat them as forbidden) so that
checkIfPathIsForbidden does not silently allow non-file Desktop targets; ensure
changes reference methodsWhichCanReadFiles, methodsWhichCanExecuteFiles,
JavaInstrumentationAdviceFileSystemToolbox.variableToPath and
checkIfPathIsForbidden and cover Desktop methods
open/edit/print/browse/browseFileDirectory.
In `@src/main/java/de/tum/cit/ase/ares/api/util/ProjectSourcesFinder.java`:
- Around line 95-103: The current logic in ProjectSourcesFinder prematurely
returns null when a <sourceDirectory> element exists but its text content is
empty; change the handling in the method that reads sourceDirectoryNodes (the
block that returns toRelativeSourceDirectory(sourceDirectoryPropertyValue)) to
treat blank/whitespace-only values as if the element were absent (i.e., trim and
check length > 0 before returning), so the default fallback
(DEFAULT_MAVEN_SOURCE_DIRECTORY) can be used; apply the same blank-check fix to
the analogous block around the code flagged at lines 110–113.
In
`@src/test/resources/de/tum/cit/ase/ares/integration/testuser/securitypolicies/java/maven/archunit/aspectj/PolicyOneNetworkConnectionAllowed.yaml`:
- Around line 11-16: The policy's network connection entry under
regardingNetworkConnections currently uses onThePort: 12345 causing tests to
target the wrong echo server; update the entry (the object with onTheHost,
onThePort, openConnections, sendData, receiveData) to use the external loopback
echo-server port 25565 (keep onTheHost as "127.0.0.1" and preserve the other
flags) so the integration tests connect to the expected external echo server.

Thread"; update assertThreadErrorMessage to verify the passed operationText is
present in actualMessage instead of the fixed "create Thread" string (e.g.,
replace the assertTrue(actualMessage.contains("create Thread"), ...) with an
assert that actualMessage.contains(operationText) and include operationText in
the assertion failure message); ensure assertThreadSecurityException still
passes the intended operationText through to assertThreadErrorMessage and
consider a null-check/fallback if any callers pass null so tests remain
deterministic.
In

Fail-closed is required when the command-carrying field cannot be inspected
Line 489 currently downgrades reflection failures to null, which can let ProcessBuilder.start() bypass command allowlist enforcement when command is unreadable. This turns an enforcement failure into an allow decision.
Suggested fix (fail closed for critical command field reads)
- `@Nonnull` Object[] attributes = new Object[0];
+ `@Nonnull` Object[] attributes = new Object[0];
+ boolean criticalCommandFieldUnreadable = false;
+ String signatureWithoutModifiers = extractMethodNameWithoutModifiers(fullMethodSignature);
if (instance != null) {

Don't exempt every student-supplied java.home read.
This helper now treats any read under java.home as trusted and Line 943 skips the violation entirely. That means student code can read arbitrary JDK files just by passing paths like ${java.home}/release or ${java.home}/conf/security/java.security, even when the policy does not allow them. The exemption needs an internal-origin signal or a much narrower path check; otherwise both the AspectJ path here and the mirrored instrumentation path become an allowlist bypass.
Also applies to: 943-945

In
`@src/main/java/de/tum/cit/ase/ares/api/aop/java/aspectj/adviceandpointcut/JavaAspectJFileSystemAdviceDefinitions.aj`
around lines 109 - 127, isExemptSystemFileAccess currently exempts any "read"
under java.home, which lets student code read arbitrary JDK files; update the
helper (method isExemptSystemFileAccess and any call sites like the AspectJ
pointcut at lines referenced) to stop blanket-allowing reads: either require an
explicit internal-origin signal/flag passed into isExemptSystemFileAccess (or
set by the JVM-internal call path) before returning true for "read", or narrow
the allowed read paths to a tight allowlist of specific JVM-only
files/directories (e.g. specific conf/security or native/lib paths) and only
return true when path matches those exact allowed subpaths; also ensure
NATIVE_LIBRARY_SUFFIXES handling remains unchanged for "execute".

Do not collapse java.awt.Desktop into the “read” file-system bucket.
JavaInstrumentationPointcutDefinitions.methodsWhichCanReadFiles includes java.awt.Desktop (open/edit/print/browse/browseFileDirectory) while methodsWhichCanExecuteFiles omits it, so the Byte Buddy instrumentation applies checkFileSystemInteraction("read", ...) to these calls. In JavaInstrumentationAdviceFileSystemToolbox.variableToPath, URI/URL values are only converted for file:/file schemes; otherwise it returns null, and checkIfPathIsForbidden returns false when target is null—so non-file: Desktop targets bypass the read allowlist path checks entirely.
Move java.awt.Desktop to an appropriate action/bucket (or add explicit handling that blocks or correctly validates non-file: URI/URL arguments) instead of relying on the "read" policy.

Fix java.net.URL.openStream classification (still treated as file-read). java.net.URL.openStream remains in methodsWhichCanReadFiles (entry at ~line 377) and is therefore bound to the file-read advice (JavaInstrumentationReadPath*Advice → JavaInstrumentationAdviceFileSystemToolbox.checkFileSystemInteraction("read", ...)), while it is absent from methodsWhichCanConnectToNetwork (~lines 597–598). Move openStream out of the read pointcuts and into the appropriate network connect/receive pointcuts so URL fetches are controlled by network policy rather than file-read policy.

Avoid early null return when <sourceDirectory> is present but blank.
At Line [95]–Line [98], a blank <sourceDirectory> returns null immediately, so the default fallback at Line [101] is never reached. That can incorrectly disable source-path discovery for otherwise valid Maven defaults.
Suggested patch
- if (sourceDirectoryNodes.getLength() > 0) {
- var sourceDirectoryPropertyValue = sourceDirectoryNodes.item(0).getTextContent();
- return toRelativeSourceDirectory(sourceDirectoryPropertyValue);
- }
+ if (sourceDirectoryNodes.getLength() > 0) {

Use the external echo-server port in this policy.
Line 13 currently allows 12345, but the integration contract uses loopback echo on 25565; this can cause spurious connection failures in tests that should validate policy behavior.

Summary
This branch stabilises the Ares 2 test suite and the Maven CI pipeline. It fixes a number of real production bugs in the AOP and architecture enforcement layers, repairs the build/format gate, migrates the integration test users off the defunct Ares 1 annotations onto
@Policy, and corrects a large amount of test/fixture/policy drift. Compared with the starting point on this branch, the full-suite failures are down from 188 failures / 38 errors to 121 failures / 18 errors, with several whole test classes now green (JqwickTest,NetworkTest,InputOutputTest, the allowed file-system read/overwrite/delete operations, the precompile flow, and the architecture file-system forbidden tests in isolation).Changes
spotless:applysospotless:check(the first CI step) passes; add the CI job timeout, surefire fork timeout, heap cap and JVM module-access args.java.awt.Desktopinterception to the file-read check only (was bound to read/overwrite/execute/delete at once, giving a nondeterministic verb); stop misclassifyingjava.net.URL.openStreamandjava.net.URI.createas network access; exempt JDK-internal reads underjava.home(e.g.JceSecurityreading the crypto policy files) from the file-system checks; add denial reasons to theSecurityExceptionmessages; fix loopback/IPv6 network-target parsing. Changes are applied symmetrically across the AspectJ and instrumentation layers.SecurityExceptionso a cache read inside an active policy can no longer poisonJavaWalaTestCase(and every subsequent WALA test) withNoClassDefFoundError; exclude Ares's own engine classes from student architecture analysis.@WhitelistPath,@BlacklistPath,@AllowThreads,@AllowLocalPort,@TrustedThreads,@WhitelistClass/@WhitelistPackage,@BlacklistPackage,@AddTrustedPackage) onto active@Policydefinitions; pin the English locale for AOP/thread tests; connect the network test to an external echo server instead of an in-JVM one; correct the forbidden file-system within-paths and assertions; add the trusted/nottrusted delete fixtures; let theSecurityExceptionpropagate from forbidden thread subjects; write the precompile scaffold into a temporary directory so the repository is no longer polluted.Rationale
The Ares 2 enforcement model moved entirely to
@Policy-driven architecture and AOP analysis; the test suite still carried a large amount of Ares 1 era state (defunct annotations, stale paths, an in-JVM echo server, generated artefacts written into the repo) and several genuine production bugs surfaced only under the full suite. The production fixes address real correctness issues (operation misclassification, a class-initialiser poisoning bug, JDK-internal reads being blocked), while the test changes realign the suite with the current production behaviour and make it reproducible.Known remaining work
aop.allowed.FileSystemAccessExecuteTest(38F/16E): the Execute bucket still needs its subjects pointed at the policy-permitted trusted script plus the missing fixtures; not yet started.aop.forbiddenfile-system (44F/2E): remaining classification/assertion fixes.ThreadTest+architecture.forbidden.ThreadSystemAccessTest(11F): an AOP thread-interception gap (Thread.sleep, parallel streams,Thread.run(), Flow publisher).forkCount=1,reuseForks=true). The architecture file-system forbidden tests are green in isolation (200 run, 0 failures) but fail in the full run because the WALA analysis is affected by global state left by earlier tests. Resolving this (e.g.reuseForks=false, weighed against the CI time budget, or fixing the WALA reentrancy) is the highest-leverage next step and would clear roughly a third of the remaining failures.Summary by CodeRabbit
