Rebuild and run the TablePerClassInheritanceTestSuite Using an EmbeddedId on classes using @Inheritance(strategy=TABLE_PER_CLASS) causes Exception [EclipseLink-74] (Eclipse Persistence Services - 2.2.0.qualifier): org.eclipse.persistence.exceptions.DescriptorException Exception Description: The primary key fields are not set for this descriptor.

Is this just based on project development testing or does it effect user.
I have the same issue. This bug is very critical to me as im porting a working application from JBoss to Equinox and I cannot change the mapping or class model. This bug effectively makes the porting to Equinox using Eclipse Link impossible to me.
Targetting for 2.2. We will take a look at this in the next few days and assuming the fix is fairly straight-forward, we will check in a fix (else we will add some comments)
Created attachment 181100 [details] Proposed changes
Changes have been submitted. Reviewed by: Chris Delahunt Added new model to the inheritance package. With fix in place, metadata processing completes without errors and the full regression and extended tests all pass.
