Marcel Reutegger commented on JCR-688:
--------------------------------------
I think the patch is very good, I just have one issue: name resolution through
the CachingNameResolver is serialized. The call resolver.getQName(name) within
CachingNameResolver.getQName() is in a synchronized(this). Can this be change
in a way that multiple thread can resolve names concurrently?

> 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.
