HSQLDB gets primary key constraint on multiple job cleanup
----------------------------------------------------------
Key: CONNECTORS-249
URL: https://issues.apache.org/jira/browse/CONNECTORS-249
Project: ManifoldCF
Issue Type: Bug
Components: Framework core
Affects Versions: ManifoldCF 0.3
Reporter: Karl Wright
Fix For: ManifoldCF 0.3
Create two jobs which overlap. Crawl both of them. Then delete one, and then
the other. You will get stack traces like this:

This only happens on HSQLDB, and is probably related to CONNECTORS-248 and
CONNECTORS-246.
