Flavio Junqueira commented on ZOOKEEPER-1733:
---------------------------------------------

I ran it and checked the logs. The triple election test is just not completing. 
It goes through the first and the second rounds, but after the second leader 
dies, it doesn't elect the third. It needs some more investigation, I don't 
think removing the check as you suggest actually fixes it.

> FLETest#testLE fail intermittently on windows boxes. The reason is that in 
> LEThread#run() we have:
> {code}
>                                 if(leader == i){
>                                     synchronized(finalObj){
>                                         successCount++;
>                                         if(successCount > (count/2)) 
> finalObj.notify();
>                                     }
>                                     break;
>                                 }
> {code}
> Basically once we have a confirmed leader, the leader thread dies due to the 
> "break" of while loop. 
> While in the verification step, we check if the leader thread alive or not as 
> following:
> {code}
>        if(threads.get((int) leader).isAlive()){
>            Assert.fail("Leader hasn't joined: " + leader);
>        }
> {code}
> On windows boxes, the above verification step fails frequently because leader 
> thread most likely already exits.
> Do we know why we have the leader alive verification step only lead thread 
> can bump up successCount >= count/2?
