[infinispan-issues] [JBoss JIRA] Commented: (ISPN-752) ClassCastException during rehash if join RPC has any exceptional responses

[Scott Marlow (JIRA)]

    [ https://jira.jboss.org/browse/ISPN-752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12560968#action_12560968 ] 

Scott Marlow commented on ISPN-752:
-----------------------------------

I also hit a NPE rehash issue.  http://pastebin.com/E237tmY8

I was going to create a new jira but it also seems to be doing a org.infinispan.distribution.JoinTask.performRehash.  Let me know if it deserves a separate jira

> JoinTask.updateTopologyInfo(...) assumes all responses from a JOIN_REHASH_START will be SuccessfulResponse's.  ExceptionResponse's are not handled and cause a CCE.
