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

Craig-
You're right that the classes shouldn't be final, but I don't think that's the cause of the problem. 


I've committed a fix to the final class issue, though. Thanks for  
pointing it out.

Hi Kevin,


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. "


The relevant part of the stack trace appears to be:

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

which sounds like an issue with the xerces parser. Don't you hate  
exceptions from parsers rather than error messages?

Kevin-

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

with deserializing the default model from the companies.xml file  
from

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

update and re-run the test and let us know if the stack trace  
changes?
