> A ConcurrentModificationException is thrown when a resource shuts down.
> removeEntry method is unsafly accessing _entriesByMemberEPR data member.
> I think following methods should be synchronized since they all access
> _entriesByMemberEPR:
> public WsResource addEntry(EndpointReference memberEPR, WsResource entry)
> public WsResource[] getEntry()
> public WsResource getEntry(EndpointReference memberEPR)
> public void removeEntry(WsResource entry)
> Exception stack trace:
> java.util.ConcurrentModificationException
> at java.util.HashMap$HashIterator.nextEntry(HashMap.java:841)
