[Jiri Peterka (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-11522?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12687921#comment-12687921 ] 

Jiri Peterka commented on JBIDE-11522:
--------------------------------------

I met this error again, these steps are probably better for replication:
1. jpa project (added hb 4.0 jars from another general project) 
2. Hibernate console is set to 3.5, generated entities from DB (hsqldb 1.8)
3. Select entity "Customers" in Configuration Tree item in Hibernate Configuration
4. open HQL editor
5. run default query
6 when switched to HB 4.0 in console and repeat of steps 3.-5., there is error from above
