Synchronization on 'this'
Reports synchronization which uses
this as its lock expression.
Constructs reported include
synchronized blocks which lock
this, and calls to
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.
