New Revision: 414756

URL: http://svn.apache.org/viewvc?rev=414756&view=rev
Log:
Local caching of client paginated lists is broken 
 
 * on the remote client, paginated query is intercepted before the local cache, 
thus local cache settings are ignored.
 * on the server: RemoteIncrementalFaultList overrides the query cache key, so 
cached IncrementalFaultLists can't be reused and a new list created on every 
query, taking lots of memory.

(I can't log in to Jira due to Apache network problems; I will enter the bug 
once this is resolved)
