Modeshape unit test JpaConnectorNoCreateWorkspaceTest freezes when Oracle is used as database. Test did not end even after 8 hours of running, it had to be aborted. The expcetion in test log is: java.sql.SQLException: READ_COMMITTED and SERIALIZABLE are the only valid transaction levels.

Tested with Oracle 11g R2 and Oracle 10g.
