Stuart Douglas commented on AS7-970:
------------------------------------
Just looking at the interceptor is looks like tryLock() is being called multiple times but
unlock() is only called once. We need to check if the lock is already held before calling
tryLock.
There is also the possibility in many places for an exception to leave the lock locked.
