Synchronization on 'this'

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.
