ClassLoader leak in org.jboss.el.cache.FactoryFinderCache --------------------------------------------------------- Key: WFLY-3365 URL: https://issues.jboss.org/browse/WFLY-3365 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Class Loading, EE Affects Versions: 8.1.0.CR2 Reporter: Björn Sköld Assignee: Tomaz Cerar Fix For: 9.0.0.Alpha1 Attachments: leak.zip After deploy/undeploy of a webapp that uses org.jboss.el, a reference to the webapp classloader remains in FactoryFinderCache. I currently work around this by calling FactoryFinderCache.clearClassLoader in a ServletContextListener. Uncommenting line 26 in LeakListener makes the reference go away on undeploy.
