I have somehow managed to make hibernate crash with the NPE below. Hibernate tries to carry out the following code:
throw new MappingException("entity pojo class not found: " + entity.getEntityName(), cnfe);

But for some reason the variable "entity" is null. Has anyone got a hint to what I could be doing wrong? Why would the parameter "entity" be null when H3 expects it not to be?

Is this a known bug?

Note to the developers: The error above occured because I had declared a joined-subclass in an hbm file using a non-existing package name. I simply changed the fully qualified class name and the problem was gone.

Looking at the Hibernate code for PersistentClass.getMappedClass() I came to the conclusion that the statement shown in my previous post should have used the class name String instead of entity.getEntityName() which (as I have showed) may lead to a NPE.

AFAIK already fixed in cvs.

That 's great Max!

Thanks.
