@TableGenerator throws Unsupported exception - error performing isolated work
-----------------------------------------------------------------------------

                 Key: HHH-5019
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5019
             Project: Hibernate Core
          Issue Type: Bug
    Affects Versions: 3.3.1, 3.3.0.SP1, 3.3.0.GA, 3.3.0.CR2, 3.3.0.CR1, 3.2.7, 3.2.6, 3.2.5, 3.2.4.sp1, 3.2.4, 3.2.3, 3.2.2, 3.2.1
         Environment: Hibernate Core 3.3.1, MySQL, Websphere 6.1 with EJB3.0 Feature pack
            Reporter: Rohini


While implementing GenerationType.TABLE strategy with Hibernate as the persistence provider, id generation throws 

javax.persistence.PersistenceException: org.hibernate.HibernateException: error performing isolated work
[3/18/10 14:40:41:533 IST] 0000002d SystemErr     R 	at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:614)
--------------------------------------------------------------
3/18/10 14:40:41:533 IST] 0000002d SystemErr     R Caused by: org.hibernate.HibernateException: error performing isolated work
	at org.hibernate.engine.transaction.Isolater$JtaDelegate.delegateWork(Isolater.java:166)
	at org.hibernate.engine.transaction.Isolater.doIsolatedWork(Isolater.java:64)
	at org.hibernate.engine.TransactionHelper.doWorkInNewTransaction(TransactionHelper.java:74)
	at org.hibernate.id.MultipleHiLoPerTableGenerator.generate(MultipleHiLoPerTableGenerator.java:210)

Looking at the 
Isolater.doIsolatedWork( work, session );, implementation

try {
// First we need to suspend any current JTA transaction and obtain
// a JDBC connection
surroundingTransaction = transactionManager.suspend();
	if ( log.isDebugEnabled() ) {
	log.debug( "surrounding JTA transaction suspended [" + surroundingTransaction + "]" );
				}
This happnes only with WebsphereExtendedTransactionManagerLookup as the hibernate.transaction.manager_lookup_class.
