threading problem

[fadi mujahid]

Hello
I am almost done with my SCJD assignment and I am testing it thoroughly. I am facing the following problem that is occuring randomly:
I am using wait(), notifyAll() for my lock/unlock operations.
Randomly, one of the threads gets stuck in the wait() status and wouldn't gets activated although I call notifyAll at the unlock.
Any suggestion?

Are you sure that your unlock is being called, even if an exception occurs?

hi fadi,
instead of catching for specific exceptions try to catch Throwable and print the stacktrace of it to track down things .. am sure something exception is going un noticed in your coded creating these problems.
hope this helps,

cheers,

Hello
Thank you very much for your help. I finally figured it out: I was wait()ing the object Data, and notifyAll() on object locks!!!
This stupid problem cost me more than 20 hours of debugging.
Thanks again
