angela commented on JCR-688:
----------------------------

i guess, this issue will be covered by  issue JCR-1169 Distribution of commons classes.

The proposed distribution replaces the *Format classes by  the *Resolver interfaces. Both
interfaces and jukkas implementations are copied to the spi-commons. The Parsing*Resolver
got adjusted according to tobis feedback.

> 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.
