-------------------------------------

    Resolution: Won't Fix

Resolving as won't fix as this is probably not the "correct" way to use jackrabbit

> This patch relates to JCR-890. The current implementation allows to share a session across multiple threads reading, but the locking mechanism used makes this use-case slow. The attached patch uses a ReentrantReadWriteLock for accessing session internals, which allows concurrent reads be executed concurrently. The only drawback is, that for the "autofix" feature to work as before one has to instantiate a thread on such cases, because it cannot be executed in the read-scope of a the session facing such problems.
