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

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.

>          Components: Eviction
>    Affects Versions: 5.2.3.Final

>            Priority: Critical

> Here's the scenario:
> Given 2 nodes with REPL_SYNC cache with passivating cache store (e.g. default web cache in AS7).
> 1. Create cache entry containing atomic map with 2 map entries on node1.
> 2. Passivate that cache entry on node2 via manual evict.
> 3. Modify 1 of the atomic map entries within the cache entry on node1.
> 4. Lookup atomic map on node2.  It only contains 1 map entry - the map entry modified in step 3.  The other map entry is lost.
> It's a side effect of ISPN-2384, where some changes were made to tighten the passivation/activation scenarios, but it did not cover manual eviction calls.
