> JSF application's classes are not unloaded properly when undeployed. The test case is in the attachment. Steps to reproduce:
> # mvn package
> # deploy war-leak.war
> # open http://localhost:8080/war-leak
> # undeploy war-leak.war
> # analyze a heap dump to find unloaded ModuleClassLoader of war-leak.war
> References to the WAR classes are hold by java.beans.Introspector caches. It seems to be a known bug (feature?). For example Tomcat automatically invokes java.beans.Introspector.flushCaches() when WAR undeploys. There is also IntrospectorCleanupListener in Spring for the same purpose.
