Hi guys,
I had an application working fine with OpenJPA, but I decided to migrate to Hibernate and I get a Null pointer exception (see the attached stacktrace).
Let me know if you need some other info. My configuration is below:
persistence.xml:

Java, 1.6, Spring 3.0.0 (tested also with 3.0.1.SNAPSHOT)
Is this still a problem with 3.5.1?
I see from your stacktrace that the NullPointerException happens when the ORDER BY clause of a query is being parsed.
What is the query that is failing?
