Description Christoph Laeubrich CLA 2011-09-24 02:57:17 EDT 
Build Identifier: 2.3.0.v20110604-r9504

If you add an orm.xml mapping to mark a (for example generated) java class as a mappedsuperclass and the derive from this class and mark it with annotation the EntityManager fails with a null-pointer on schema generation.

Described in more detail here: http://www.eclipse.org/forums/index.php?t=rview&goto=726870

Doing everything with annotations works fine.

Reproducible: Always

Steps to Reproduce:
Described here: http://www.eclipse.org/forums/index.php?t=rview&goto=726870

Workaround:
As mentioned by James "To workaround the issue try defining both in XML or both in annotations."
Comment 1 Guy Pelletier CLA 2011-09-28 10:11:49 EDT 
This is a duplicate of bug 349906.

If possible, please try/use a nightly build of 2.3.1

http://www.eclipse.org/eclipselink/downloads/nightly.php

Otherwise, the work around as James suggested is to include the entity in XML as well (just declare it in XML)

e.g.

<entity class="PersistentLabResultType"/>
