> Timing bug in rg.apache.excalibur.thread.ThreadControl.join()
> -------------------------------------------------------------

> Key: EXLBR-1
> URL: http://issues.apache.org/jira/browse/EXLBR-1
> Project: Excalibur Components
> Type: Bug
> Components: Thread
> Environment: Mandrake 9.2 on Compaq Armada E500
> Reporter: Pradeep Krishnan
> Assignee: Shash Chatterjee
>
> The ThreadControl implimentation in
> org.apache.excalibur.thread.impl.DefaultThreadControl has a timing bug in the
> join() function. There is a small timing window between the time the worker
> thread has finished executing and before a call to the finish() method of the
> ThreadControl is made. This can cause the threads waiting on a join(0) to
> never wake-up.
> The patch is simple: instead of delegating the join() to the m_thread, do a
> wait(). The finish() method of the
> org.apache.excalibur.thread.impl.DefaultThreadControl does a notifyAll() and
> that should wake up the calling thread.
