[jboss-jira] [JBoss JIRA] (AS7-6967) ClassLoader memory leak with JSF

ClassLoader memory leak with JSF -------------------------------- Key: AS7-6967 URL: https://issues.jboss.org/browse/AS7-6967 Project: Application Server 7 Issue Type: Bug Components: JSF Affects Versions: EAP 6.1.0.Alpha (7.2.0.Final) Reporter: Vlad Arkhipov Assignee: Stan Silvert Priority: Critical Attachments: war-leak.tar.gz 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. http://wiki.apache.org/commons/Logging/UndeployMemoryLeak http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/...
