[jboss-jira] [JBoss JIRA] (AS7-3340) NPE during stop of service jboss.jacorb.poa-service.rootpoa

[Pavel Janousek (JIRA)]

    [ https://issues.jboss.org/browse/AS7-3340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12664087#comment-12664087 ] 

Pavel Janousek commented on AS7-3340:
-------------------------------------

Today I got this exception after 8 minutes long run of EAP, so it seems it isn't related to quick stopping after startup (see last attempt of start/stop sequence in AS7-3606).
