Upgrade from 3.0.6 to 3.2.3 breaks trivial ejbSelect

[rstinejr]

Upgrading from 3.0.6 to 3.2.3 results in a null pointer exception in the generated code of the following trivial ejbSelect method:


<query-method>
<method-name>ejbSelectFoo</method-name>
<method-params>
<method-param>java.lang.Integer</method-param>
</method-params>
</query-method>
<ejb-ql><![CDATA[SELECT OBJECT(f)
FROM Foo f
WHERE f.fooId =?1]]></ejb-ql>


I verify that I'm not passing a null argument before trying to call ejbSelectFoo.

Any ideas, other than the obvious one of reverting to 3.0.6?

More info: the NPE is getting thrown by org.jboss.ejb.plugins.cmp.jdbc.JDBCAbstractQueryCommand; the pertinent part of the stack trace is:

java.lang.NullPointerException

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.
 EntityContainer selectContainer = selectManager.getContainer();
 if (queryMetaData.isResultTypeMappingLocal())
 {
 LocalProxyFactory localFactory = selectContainer.getLocalProxyFactory();
 return localFactory.getEntityLocalCollection(results);
 }
 else
 {
 EJBProxyFactory factory = selectContainer.getProxyFactory();
 return factory.getEntityCollection(results); // <<<<< line 273
 }

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

There is nothing neither wrong nor special in this query. It should work. How can I reproduce it? Do you have a testcase?
