> A DESCRIPTION OF THE PROBLEM :
> The API spec for Thread.sleep(long) and Thread.sleep(long, int) claims
> that it throws InterruptedException "if another thread has interrupted the 
> current thread".
>
> First, this sentence is misleading, as a thread can interrupt itself. So it
> should read "if any thread has interrupted the current thread."
>
> Secondly, the implemetation fails according to this specification.
> If Thread.sleep(0) or Thread.sleep(0,0) is invoked, InterruptedException
> is *never* thrown, even if the thread has been interrupted.
>
> Please either fix this bug or "fix" the spec (as Sun often prefers to do).
>
>
>
> STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
> Compile and run this program:
>
> public class zz {
>         public static void main(String[] args) throws Exception {
>                 Thread.currentThread().interrupt();
>                 Thread.sleep(0, 0);
>         }
> }
>
>
>
> EXPECTED VERSUS ACTUAL BEHAVIOR :
> EXPECTED -
> InterruptedException thrown
> ACTUAL -
> No exception thrown.
>
> REPRODUCIBILITY :
> This bug can be reproduced always.
