      Unfortunately I cannot provide the code or data, as that is confidential. However, I believe that similar conditions could be achieved by modifying the new StatelessBeanManagedTransactionBean integration test, so that it creates many more nodes, and increasing the "batch" size to, say, thousands of nodes per save()/commit(), and then attempting to perform a concurrent SQL2 query. Specifically, attempt to query for a node by an equals condition on a property, for one of the nodes that is being saved. Sorry I cannot be more helpful.

      NPE encountered when invoking an SQL2 query via the REST service, while an asynchronous EJB, with BMT, is updating the repository. Specifically, it appears that the EJB is executing either Session.save() or UserTransaction.commit() when the exception is encountered. If the EJB is not executing save() or commit(), but doing other things, the query works correctly.

      The exception is below:
