Line 273 of method JDBCAbstractQueryCommand.java, with a little context, is:
| // This is an ejbSelect, so we need to convert the pks to real ejbs.
| EntityContainer selectContainer = selectManager.getContainer();
| if (queryMetaData.isResultTypeMappingLocal())
| {
| LocalProxyFactory localFactory = selectContainer.getLocalProxyFactory();
| return localFactory.getEntityLocalCollection(results);
| }
| else
| {
| EJBProxyFactory factory = selectContainer.getProxyFactory();
| return factory.getEntityCollection(results);
| }

| // This is an ejbSelect, so we need to convert the pks to real ejbs.

Desk checking this (I haven't run JBoss itself thru the debugger), it appears that
selectContainer.getProxyFactory() is returning a null.
