Dennis Reed commented on JGRP-1921:
-----------------------------------

Later versions (I checked 3.0.9) are not affected, as they do not set done=false in execute().

> Race condition in GroupRequest can make it wait for the full timeout even after all responses are received.
> GroupRequest.execute broadcasts the request, sets "done=false", then waits for a reply.
> If all the replies come in before it sets done=false, it will overwrite the done=true set by the responses and wait for the full timeout, and then return false.
> Note that the internal uses by MessageDispatcher/etc do not check the return value from execute, so this does not affect the data returned, only how long the call blocks for.
