[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1056) Cache.stop() method raise a exception on application termination

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1056?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12600132#comment-12600132 ] 

Galder Zamarreño commented on ISPN-1056:
----------------------------------------

Thanks Paolo. Seems like there really is not anything else in the file.

Anyway, apart from my suggestion earlier, this can possibly be fixed in a much easier way by having a boolean volatile that is set to true when CacheManager.stop() is called, and if another comes through, instead of bypassing potentially stopping caches and stop the global component registry, it would simply ignore the call to CacheManager.stop(). That way, only the initial thread that called CacheManager.stop() will stop the global component registry once all caches are stopped which should stop the NPE.
