[infinispan-issues] [JBoss JIRA] Commented: (ISPN-630) NullPointerException during object unmarshalling

[Sanne Grinovero (JIRA)]

    [ https://jira.jboss.org/browse/ISPN-630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12549360#action_12549360 ] 

Sanne Grinovero commented on ISPN-630:
--------------------------------------

sounds like a good plan. If you add the logging to some branch (4.1.1? 4.2? 5?) I'll be able to start the stresstest system pointing to that, but that will have to wait until next weekend.
