Getting the error "Cannot change transaction isolation level in the middle of a transaction."

See attached patch for a configuration that will make continuum store test fail using atomikos and postgres 8.3

javax.jdo.JDODataStoreException: Error while obtaining connection for POID generation : Cannot change transaction isolation level in the middle of a transaction.
