[jbosstools-issues] [JBoss JIRA] (JBIDE-10501) NPE in HibernateExtension4_0.executeHQLQuery() when trying M5a and Hibernate 4

[Dmitry Geraskov (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-10501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12651659#comment-12651659 ] 

Dmitry Geraskov commented on JBIDE-10501:
-----------------------------------------

The exception shows that at the time of the execution sessionFactory is null. But we check sessionFactory is not null on ConsoleConfiguration before the execution. So the reason is unsychronized ConsoleConfiguration and HibernateExtension states. (HibernateExtension #sessionFactory is null while ConsoleConfiguration is not). Seems I was able to find a way to achieve this. Just need to run exporters after session factory was build but before query execution. I'll check my assumption.
