> We have a @MappedSuperclass that is the base for all of our entity bean
> classes. This class contains the @Version (and @Column for the version
> field) that all of our entity beans use. But, in
> ClassMetaData.validateAppIdClass(), if an entity bean class has a superclass,
> and the entity bean has an @IdClass, it expects that superclass to have an
> @IdClass also. All of our entity beans have an @IdClass (even if they only
> have a single part key), but our @MappedSuperclass does not have an @IdClass.
> This scenario works under JBoss 4.2.0 and Sun AS 9, but produces a
> NullPointerException in OpenJPA at:
> if (_super != null) {
> // concrete superclass oids must match or be parent of ours
> ClassMetaData sup = getPCSuperclassMetaData();
> if (!sup.getObjectIdType().isAssignableFrom(_objectId)) // <---
> NullPointerException here
