GroovySynchronizationOnThis

Reports synchronization which uses this as its lock expression.

Constructs reported include synchronized blocks which lock this, and calls to wait()``notify() or notifyAll() which target wait(). Such constructs, like synchronized methods, make it hard to track just who is locking on a given object, and make possible "denial of service" attacks on objects. As an alternative, consider locking on a private instance variable, access to which can be completely controlled.
