Mappings with foreign keys as identity fields sometimes not resolved correctly
------------------------------------------------------------------------------
Key: OPENJPA-1736
URL: https://issues.apache.org/jira/browse/OPENJPA-1736
Project: OpenJPA
Issue Type: Bug
Components: jdbc
Affects Versions: 2.0.0
Reporter: Martin Dirichs
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.
