Full Changelog: v8.21.0...v8.22.0

Version 8.21.0

New features and improvements

• Enhances visibility into Reactor Mono.flatMap calls by @deleonenriqueta in #2308
• Adds new instrumentation for Spring-Kafka and distributed tracing when using the core Kafka client library by @obenkenobi in #2312
• Adds KafkaConsumerConfig event support for Kafka 3.7+ by @nrlkirby in #2358

Fixes

• Fixes the distributed_tracing.sampler config by @jbedell-newrelic in #2330

• Fixes an Illegal Access Error that can occur when using Scala 2.12 and JDK 11. In cases where Scala 2.12 is not detectable by the agent (we check the system classloader for this - notably, sbt will load Scala classes into custom Scala loaders), there is also a feature flag to manually enable the fix via system property -Dnewrelic.config.class_transformer.illegal_access_fix=true by @kanderson250 in #2334

• Fix netty 'Unknown' transactions 2274 2355

  • This fix moves previous netty instrumentation changes behind a feature flag, which provides additional visibility in some cases involving HTTP2 transactions. To reenable this granularity (at the possible cost of seeing ‘Unknown’ transactions), use the config setting:

    netty:
      http2:
        frame_read_listener:
          start_transaction: true

  • 8.20 has a logic error in the agent config so the fix is only official in agent version 8.21 and up.

• Adds a restriction on when to add distributed trace headers for SQS messages. This is based on how large the contents of a message is in bytes and the and the size of attributes. Messages with size greater than 251 KB and/or with 9 or more attributes are excluded from getting distributed trace headers added by @obenkenobi in #2353

• Allows the org.crac JAR to be shadowed to prevent conflicts with customer environments. by @jbedell-newrelic in #2344

• Backports changes made in PR #1927 to prevent NullPointerExceptions to older versions of the vertx-core instrumentation by @jgoulard in #2327

• Prevents excessive transaction segments from being created by HttpUrlConnection method calls (e.g. getInputStream) when they are not associated with an external call. This behavior can be controlled by the following config options: NEW_RELIC_CLASS_TRANSFORMER_COM_NEWRELIC_INSTRUMENTATION_HTTPURLCONNECTION_VERBOSE=false, sys prop -Dnewrelic.config.class_transformer.com.newrelic.instrumentation.httpurlconnection.verbose=false, or equivalent stanza in newrelic.yml. Default setting is true (i.e. non-external getInputStream and other response handler methods will be reported as before). by @kanderson250 in #2365

Security

• Upgrades the com.newrelic.agent.java:infinite-tracing-protobuf for better security with infinite tracing by @jtduffy in #2339
• Replaces snakeyaml with com.konloch:safeyaml to address a security vulnerability by @jtduffy in #2333

Deprecations

The following instrumentation modules are deprecated and will be removed in the next major release:

• aws-wrap-0.7.0
• java.completable-future-jdk8
• play-2.3
• netty-3.4
• Struts v1

CSEC Version Update to 1.7.0 by @lovesh-ap in #2348
Changelog: https://github.com/newrelic/csec-java-agent/releases/tag/1.7.0

Full Changelog: v8.20.0...v8.21.0

Version 8.20.0

New features and improvements

• Support for CRaC 2250

• Support for JDK24 2284

• Add sampling options when an inbound traceparent exists 2279

  • These options define how the agent should handle sampling of spans, depending on sampling decisions that were made for their parent span by an upstream entity. The configuration options remote_parent_sampled and remote_parent_not_sampled specify what to do in the case the parent span was sampled or not sampled, respectively. See the documentation for full configuration details.

• Support for Undertow as a stand-alone module 2269

  • This instrumentation is disabled by default to avoid conflicts with existing Wildfly instrumentation. To enable this instrumentation for stand-alone Undertow server apps, use the configuration setting:

   class_transformer:
     com.newrelic.instrumentation.undertow-server-1.1.0:
       enabled: true

• Support for Couchbase Client 2203

  • If the Couchbase Client Experimental Module is currently in use, remove it from your extensions directory before upgrading to this version of the Java Agent.

Fixes

• Fix netty 'Unknown' transactions 2274

  • This fix moves previous netty instrumentation changes behind a feature flag, which provides additional visibility in some cases involving HTTP2 transactions. To reenable this granularity (at the possible cost of seeing ‘Unknown’ transactions), use the config setting:

    netty:
      http2:
        frame_read_listener:
          start_transaction: true

• Refactor AWS docker id fetch to use 5s timeout 2275

• Feature flag to apply Kotlin ArrayIndexOutOfBoundsException fix to all methods 2307

  • This fix addresses errors that may be seen when running the Java Agent in an environment where Kotlin suspends functions are used. To use this fix, set the system property -Dnewrelic.config.class_transformer.clear_return_stacks=true

• Prevent cache lock for long DB statement parsing 2294

• Add config to specify whether java.sql is loaded by platform classloader 2267

Deprecations

The following instrumentation modules are deprecated and will be removed in the next major release:

• aws-wrap-0.7.0
