[infinispan-issues] [JBoss JIRA] Commented: (ISPN-779) GlobalComponentRegistry shutdown hook causing issues when servers stopped

[Galder Zamarreño (JIRA)]

    [ https://jira.jboss.org/browse/ISPN-779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12563981#comment-12563981 ] 

Galder Zamarreño commented on ISPN-779:
---------------------------------------

The issue is only present in master or trunk and this is due to me merging ISPN-496 incorrectly into the main trunk.

4.1.x: http://fisheye.jboss.org/changelog/Infinispan/?cs=1952
trunk: http://fisheye.jboss.org/changelog/Infinispan/?cs=1954

The code in Main.scala to change the shutdown behaivour is not present in trunk.

> Maybe since transaction table now removes the listener, it needs to stop *before* the cache manager notifier does?
