[jboss-jira] [JBoss JIRA] (JGRP-1684) NPE in UNICAST2.up()

[Radoslav Husar (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1684?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12801134#comment-12801134 ] 

Radoslav Husar commented on JGRP-1684:
--------------------------------------

Just to note here, we don't have a reproducer. QA has spotted the NPE in their clustering system tests. I am asking on the Bugzilla if they can provide more information or where else have they seen it.

Also I agree it's not a big deal apart from the exception in EAP log; the message gets resent and nothing is lost.
