[ http://issues.apache.org/jira/browse/JCR-688?page=all ]
Jukka Zitting updated JCR-688:
------------------------------
Attachment: JCR-688.LocalCache.patch
Attached JCR-688.LocalCache.patch (against jackrabbit-core) that replaces the
CachingNamespaceResolver in NamespaceRepository with a simple LRUMap in
LocalNamespaceMappings.
This achieves the same performance as before without any of the concurrence
issues. It also works fine with local namespace remappings.

> As discussed in JCR-685, the current CachingNamespaceResolver class contains
> excessive synchronization causing monitor contention that reduces performance.
> In JCR-685 there's a proposed patch that replaces synchronization with a
> read-write lock that would allow concurrent read access to the name cache.
