> There is a test to clear a semaphore in uima-as as part of the stop method, which does 
> {code:borderStyle=solid}
> 	// release all permits
> 	  if ( semaphore != null ) {
> 		  while ( semaphore.availablePermits() > 0) {
> 		  		semaphore.release();
> 	  	  }
> 	  }
> {code}
> Stepping through this shows that each call to release() increases (not decreases) the number of availablePermits.
> Replace with drainPermits(), which appears to be the intent.
