Non-final '@GuardedBy' field

Reports @GuardedBy annotations in which the guarding field is not final.

Guarding on a non-final field may result in unexpected race conditions, as locks will be held on the value of the field (which may change), rather than the field itself.


private ReadWriteLock lock = new ReentrantReadWriteLock(); //not final guarding field private Object state; @GuardedBy("lock") public void bar() { state = new Object(); }
