------------------------------------
Here is a GC root path from a web app's class loader. I can attach the heapdump if
you like.

Key: LOGMGR-90
URL: https://issues.jboss.org/browse/LOGMGR-90
Project: JBoss Log Manager
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 1.4.0.Final
Environment: EAP 6.1.0 and EAP 6.2.0 as well.
Reporter: Osamu Nagano
Assignee: David Lloyd
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.
