Hi! I don't think this is a safe way of resolving bugs, maybe in this case it is (but I have to look at the code), but avoid the deadlock just by removing a synchronized block means that the two threads now have a chance to get in the way of each other's data. We should instead avoid the deadlock in the first place. Maybe the problem is caused by some threads doing unrelated things, so in this case having an object to use as semaphore, instead of "this", may be of help. Can you provide an example causing the deadlock? Cheers, Mario
