[rules-users] MySQL and Derby issues with Guvnor

Hi , I have changed the defualt Derby DB to MySQL DB for the JacRabbit in Guvnor. I see this below exception when I try to bring up the JBOSS AS and Guvnor. Any idea what is the issue 2009-07-30 16:58:09,499 INFO [STDOUT] (main) ERROR 30-07 16:58:09,499 (BundleDbPersistenceManager.java:storeBundle:1270) failed to write bundle: cafebabe-cafe-babe-cafe-babecafebabe ERROR 23505: The statement was aborted because it would have caused a duplicate key value in a unique or primary key constraint or unique index identified by 'SQL090729054055150' defined on 'DEFAULT_BUNDLE'. Is there a way to get rid of JacRabbit and use more robust Implemenentation of JCR.
