Description Osamu Nagano 2014-01-07 05:25:47 UTC

Description of problem:
Web app's ModuleClassLoader is not released even after its undeployment. It seems contextMap of org.jboss.logmanager.ClassLoaderLogContextSelector object is holding the class loader's reference. If no logging-profile is configured, it doesn't leak.

Version-Release number of selected component (if applicable):
JBoss LogManager 1.4.0.Final (EAP 6.1.0) and 1.5.1.Final (EAP 6.2.0) as well.

Steps to Reproduce:
See LOGMGR-90.

Comment 1 Osamu Nagano 2014-01-07 05:30:40 UTC

contextMap is an object of CopyOnWriteMap.  I changed it to CopyOnWriteWeakMap but it didn't help.

Comment 2 James Perkins 2014-01-07 05:33:48 UTC

I was just working on this as part of https://bugzilla.redhat.com/show_bug.cgi?id=1038305. I just sent a PR for it.

Comment 3 Osamu Nagano 2014-01-07 05:47:40 UTC

Oh, I'm not aware of it.  I'll test the fix tomorrow.  Thanks.
