[jboss-dev] jboss-4.2-testsuite-sun-1.5 Build Completed With Testsuite Errors

[Brian Stansberry]

Before I tear my hair out all day, if any classloading gurus have any 
theory on why the ClassloaderLeakUnitTestCase started failing, please 
advise. Some info:

1) Started failing when I moved the test from the 'all' tests so it ran 
by itself against a clean AS.  Commit logs show nothing else relevant.

2) The test that fails involves a simple call to an SLSB over the 
UnifiedInvoker.  Deployment is a simple ejb jar. The EJB's classloader 
doesn't get cleaned up upon undeploy.

3) JBoss Profiler analysis of the leak shows that the CL is leaking to a 
Thread as the TCCL:

!--org.jboss.mx.loading.UnifiedClassLoader3 at 62812d{ url=null ,addedOrder=47}
!--!--FieldReference private java.lang.ClassLoader 
java.lang.ClassLoader.parent=org.jboss.web.WebClassLoader at ed5ba6
!--!--!--FieldReference private java.lang.ClassLoader 
java.lang.ClassLoader.parent=org.jboss.util.loading.DelegatingClassLoader at 2589c3
!--!--!--!--FieldReference private java.lang.ClassLoader 
java.lang.Thread.contextClassLoader=Thread[Thread-31,5,jboss]

Some questions I have are:

Why is org.jboss.web.WebClassLoader involved here? This deployment 
doesn't include a webapp.  (An earlier test in the class that passes did 
involve a webapp).

Is there something about running with a clean server that would change 
the relationships between the classloaders?
