Interrupt all waiting threads with Reentrant lock Java

Question

Is there any way in which I could interrupt all the threads that are waiting for lock if the thread which already acquired lock has some exception?

Answer 1

I don't think there is a good way.

If you created a subclass of ReentrantLock , that class could call getQueuedThreads() , iterate the resulting collection and call interrupt() on each one. However, that is liable to be fraught with race conditions. For example, if another thread attempts to acquire the lock while you are doing this, there is no guarantee that you will see that thread.

The second problem is figuring where and by what the exception would be detected.
