Hi Christian,
My model has more than 250 entities big. Here's the code that throws the
NLP:
Class<?> c1 = clazz1.getMappedClass();
Class<?> c2 = commonPersistentClass.getMappedClass();
MappedSuperclass commonMappedSuperclass = null;
// First we traverse up the clazz2/commonPersistentClass super types
until we find a common type
while ( !c2.isAssignableFrom( c1 ) ) {
if ( commonPersistentClass == null) {
if ( commonMappedSuperclass.getSuperPersistentClass() == null )
{ // <------------------------ NLPEX happens here!!!!!!
commonMappedSuperclass =
commonMappedSuperclass.getSuperMappedSuperclass();
commonPersistentClass = null;
}
else {
commonPersistentClass =
commonMappedSuperclass.getSuperPersistentClass();
commonMappedSuperclass = null;
}
}
else {
if ( commonPersistentClass.getSuperclass() == null ) {
commonMappedSuperclass =
commonPersistentClass.getSuperMappedSuperclass();
commonPersistentClass = null;
}
else {
commonPersistentClass = commonPersistentClass.getSuperclass();
commonMappedSuperclass = null;
}
}
}
As you can see the commonMappedSuperclass is not initialized and stays null!
At this moment c1 is CustomerEntity and c2 is UserGroupEntity. The
hierarchy looks like this:
Principal
/ \
Usergroup User
|
Customer

Hey, I saw the comment on the issue. Thanks for reporting. Could you
maybe post the model that causes this? I'd need to create a reproducer
to be able to analyze this further.
Mit freundlichen Grüßen,
