-------------------------------------------------------------

The failure in the first comment could also be related to ISPN-6399/JGRP-2028, because {{TestableCluster.killNode(Cache)}} waits only for the rehash and doesn't check the JGroups view.

Update: Normally the JGroups view shouldn't matter, because the {{REBALANCE_START}}/{{CH_UPDATE}} commands are sent asynchronously, and the coordinator doesn't wait for responses from nodes that don't have the cache. But here it is the coordinator that's leaving, and it is responsible for installing the new view for the new coordinator. So it's possible that the remaining nodes would send their {{REBALANCE_CONFIRM}} commands to the old coordinator, which wouldn't be able to process them.
