public class EntityLockInterceptor
extends AbstractInterceptor (src)

The lock interceptors role is to schedule thread wanting to invoke method on a target bean

The policies for implementing scheduling (pessimistic locking etc) is implemented by pluggable locks

We also implement serialization of calls in here (this is a spec requirement). This is a fine grained notify, notifyAll mechanism. We notify on ctx serialization locks and notifyAll on global transactional locks.

WARNING: critical code, get approval from senior developers before changing.
