Major Description
WebContainer threads are hanging due to a thread safety issue in the underlying JSF 2.0 code. A non thread-safe WeakHashMap is being used in the getRelativePath method of the DefaultFacelet class. Apache JSF 2.0 code is not synchronizing on their usage of WeakHashMap in
org.apache.myfaces.view.facelets.impl.DefaultFacelet.getRelativePath.
In order to make the code thread-safe Collections.synchronizedMap method needs to be used.
A patch has been provided.
