Bulat Nigmatullin commented on JGRP-1018:
-----------------------------------------
Our cluster consist of 15 servers. When servers upgraded they are all stopped, then new
started one by one. During some servers startup on those who already in cluster this error
occur. When error arises then joining server prints 'could not flush' and cannot
join to the cluster. After few restarts server successfully joins but others in cluster
have this errors in log files.
TP.sendToSingleMember NullPointerException
