Malformed URL for tag dependant

[Maldivia]

The dependants added in TagFileLoaderVisitor.visit() are invalid URLs, causing new URL(key) in Compiler.isOutDated() to fail with MalformedURLException, falling back to assuming that they are outdated.

Example path generated: "jar:/WEB-INF/lib/library.jar!/META-INF/sample.tld"
Causing the following exception:

DEBUG [org.apache.jasper.compiler] (default task-7) Problem accessing resource. Treat as outdated.: java.net.MalformedURLException: invalid url: /WEB-INF/lib/library.jar!/META-INF/sample.tld (java.net.MalformedURLException: no protocol: /WEB-INF/lib/library.jar)

Do you have some case how to reproduce this?

[Maldivia]

Hi, sorry for the delay.

Here's a simple war file, containing a setup that showcase this:
https://www.dropbox.com/s/zc0p229dde4ti0s/tagfile.war

The test.Test class simply throws an exception if jsp or tag class was recompiled.

Easiest way to reproduce is to enable the development mode, and set org.apache.jasper.compiler logging to DEBUG, then simply deploy above and load http://localhost:8080/tagfile and refresh.

The refresh should show you an exception, indicating that the jsp or tag class was recompiled.
And in the server.log you'll see the MalformedURLException.
