Subject svn commit: r545360 - in /openjpa/trunk/openjpa-persistence-jdbc/src/test/java/org/apache/openjpa/jdbc/kernel: EntityB.java EntityC.java TestNoForeignKeyViolation.java
Date Fri, 08 Jun 2007 01:18:41 GMT
Author: pcl
Date: Thu Jun  7 18:18:40 2007
New Revision: 545360

URL: http://svn.apache.org/viewvc?view=rev&rev=545360
Log:
Reece's test case from OPENJPA-235. I was a bit nervous about the changes to EntityB and EntityC's
relationships, but all the existing OpenJPA tests pass, so evidently we did not rely on the
particular settings as they were.
