[jboss-jira] [JBoss JIRA] Commented: (JBESB-391) sometimes the parser is not found when doing a parameter reload.
[ http://jira.jboss.com/jira/browse/JBESB-391?page=comments#action_12351563 ]
Kurt Stam commented on JBESB-391:
---------------------------------
This has to do with the undeploying the sar. When the jboss-service.xml is touched, the
sar reloads, the MBeans are stopped which call unregister on the listener and gateways.
The unregister is not successful because of classloading issues.
If the jbossesb.xml is emptied the listeners unregister nicely. This clearly is a timing
issue.
Not sure how to get around this.

The issue seems to fix it self, as it seems to be successful 5 seconds later.
