> ConcurrentStartupTest was conceived prior to implementation of a solution for JGRP-236. Upon initial integration of code for join and state transfer (JGRP-236), it was discovered that ConcurrentStartupTest was failing. Closer inspection revealed that a joining member, after joining and receiving state, would also receive messages from a previous view thus violating virtual synchrony (that is if FLUSH was present, if it was not we don't care).
