Problem summary
**************************************************************** * USERS AFFECTED: IBM WebSphere Application Server version * * 9.0 users of WebContainer * **************************************************************** * PROBLEM DESCRIPTION: A java.lang.OutOfMemoryError can be * * caused by a WebContainer map leaking * * injected objects * **************************************************************** * RECOMMENDATION: * **************************************************************** Certain types of injected objects managed by the WASAnnotationHelper are not destroyed and cleaned up properly. For example, in some common scenarios - such as defining a backing java.util.HashMap - JSF Managed Beans can leak. The hierarchy for this leak will look similar to the following: com.ibm.ws.webcontainer.annotation.WASAnnotationHelper |- java.util.concurrent.ConcurrentHashMap | '- java.util.concurrent.ConcurrentHashMap$Node[65536] | |- java.util.concurrent.ConcurrentHashMap$TreeBin | | |- java.util.concurrent.ConcurrentHashMap$TreeNode | | | |- java.util.HashMap | | | |- com.ibm.ws.cdi.impl.managedobject.CDIManagedObject
Problem conclusion
The WebContainer code has been modified to correctly destroy and clean up the injected objects that are being held. The fix for this APAR is currently targeted for inclusion in fixpack 9.0.0.8.
