-----------------------------------------
Summary: VersionVal NPEs on surrogate or missing version
Key: OPENJPA-2967
URL: https://issues.apache.org/jira/browse/OPENJPA-2967
Project: OpenJPA
Issue Type: Sub-task
Components: jpa
Affects Versions: 4.2.0
Reporter: Maxim Solodovnik
Fix For: 4.2.0
Discussion thread:
https://github.com/apache/openjpa/pull/144#discussion_r3683002730
**(medium)** `getColumns()` NPEs when the entity has a surrogate version or no
version at all (`getVersionFieldMapping()` returns null), so `VERSION(e)` on
such an entity dies with NullPointerException instead of a meaningful error -
`initialize` should validate this like it validates the class mapping. The
error at line 99 also reuses the `bad-getobjectid` message, which is misleading
for a VERSION() failure.
