     [ https://jira.jboss.org/jira/browse/JBRULES-2064?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Toni Rikkola closed JBRULES-2064.
---------------------------------

    Fix Version/s: 5.0.0.GA
       Resolution: Done


Added a better error message to the pop up.

This problem happens if classes and jars that are uploaded to Guvnor are compiled with a newer Java version than what Guvnor is running on.
