Description

This is a follow-up issue of ~~OPENJPA-1141~~. The solution developed for that issue only handled some aspects of an underlying greater problem with OpenJPAs mapping algorithm. This algorithm may fail under certain circumstances involving foreign keys used as identity fields in other entities. A patch with a test case illustrating this problem is attached to this issue. The problem can probably show up with different exceptions. However, the stack trace for the supplied test case is as follows:

testEntityAsIdentityField001(org.apache.openjpa.persistence.identity.entityasidentity2.TestEntityAsIdentityFields2) Time elapsed: 1.656 sec <<< ERROR!
<openjpa-2.0.0-r422266:935683M fatal user error> org.apache.openjpa.persistence.ArgumentException: Errors encountered while resolving metadata. See nested exceptions for details.
