Description

I've tried to use composite keys through the IdClass annotation, but the merge operation fails with the following error. I used the ApplicationIdTool to generate the IdClass object. What's odd is that I can take that exact same code and just switch the logic to use the Embeddable/EmbeddedId annotations and the merge command works.

Exception in thread "main" <openjpa-1.0.2-r420667:627158 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: The given value "idclass.CvssVector-1.0::Base" cannot be converted into an identity for "class idclass.CvssVector". The value is the wrong type (org.apache.openjpa.util.ObjectId).
