TableGenerator doesn't properly utilize all keys when under heavy stress.
-------------------------------------------------------------------------
Key: OPENJPA-1765
URL: https://issues.apache.org/jira/browse/OPENJPA-1765
Project: OpenJPA
Issue Type: Bug
Components: jdbc
Affects Versions: 2.0.0
Reporter: Rick Curtis
Assignee: Rick Curtis
TableJDBCSeq has a locking problem where multiple threads can run on top of
each other resulting in all keys not being used for a given sequence.
While unit testing a fix I also uncovered another theoretical start up problem
where multiple threads can try to insert the same row into the DB resulting in
a duplicate key exception.
