    [ https://issues.jboss.org/browse/AS7-4932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12771828#comment-12771828 ] 

RH Bugzilla Integration commented on AS7-4932:
----------------------------------------------

Jitka Kudrnacova <jkudrnac at redhat.com> made a comment on [bug 900549|https://bugzilla.redhat.com/show_bug.cgi?id=900549]

I have tested this issue with ER6 and ISPN 5.2.6.Final (taken from BZ 956988, comment 36) and the issue is still present. 

We are still seeing the NPE and we are still seeing BZ 901164 (lost sessions after failover). 

For the testing, I have chosen scenario REPL_SYNC and _graceful_ shutdown.

Looking at the test results, it looks like some of the NPE's (and the consequence 901164) were eliminated by the ISPN upgrade, but most likely there is another cause of these NPEs that was not discovered and fixed by the ISPN upgrade.  

@Rado, please elaborate on your comment on https://github.com/jbossas/jboss-eap/pull/122 : the pull 122 was made obsolete by the ISPN upgrade? Brian is asking the same thing on the pull request discussion.

> NPE is thrown in roughly 0.36% of HTTP session request processing in the test.
> This results in response code 503 returned to the client with the exception.
> The test is using passivation-enabled WAR of clusterbench
