[Martin Malina (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-13548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12758613#comment-12758613 ] 

Martin Malina commented on JBIDE-13548:
---------------------------------------

Sorry if I wasn't clear - I am able to reproduce this issue - JBIDE-13548. In JBDS 7.0.0.Alpha1b (where also vpakan was able to reproduce it), but not in JBT 4.1.0.Alpha1b (where Koen was also unable to reproduce).
[~koen.aers] is looking at it right now - discussing on IRC #jbosstools.

Koen asked if it makes sense that it's JBDS-only. And Max said:

think more its  because jpa is not being enabledautomatically.
