Re: Strange, intermittent problem running the new models.company tests

[Craig L Russell]

Hi Kevin,




The relevant part of the stack trace appears to be:

I don't know if it's relevant, but persistent classes must not be final. It seems that the entities in the model.company packages are (all) final, which is wrong. From spec 2.1, "The entity class must not be final. No methods or persistent instance variables of the entity class may be final. "

Caused by: java.lang.NoSuchMethodException: <unbound>=Class.create (Class);

Kevin-

Weird. From the error message, it looks like there is some problem

the XMLDecoder.

I've put some extra debugging logic in the CompanyModelTest.java that
should throw a better error when the deserialization fails. Can you
