Summary: LRUCachePolicy throws NPE if Trace on
Initial Comment:
LRUEnterpriseContextCachePolicy.remove() will always throw
NPE if trace deubg level is enabled. The ContextLRUList
entryRemoved() hook does a toString() on the entry, which calls
hashCode() on m_object. Of course, by this point in the remove,
m_object has been set to null...
Probably
LRUCacheEntry.toString() should check m_object for
null.
This stack trace pretty much explains it all:
