[Hibernate] PersistentSets, versions, and unnecessary updates

[Josh M. <jos...@gm...>]

Is there a known issue with versioning? There seems to be a crop of
tickets mentioning unnecessary update:

  http://opensource.atlassian.com/projects/hibernate/browse/HHH-1401
  http://opensource.atlassian.com/projects/hibernate/browse/HHH-1564
  http://opensource.atlassian.com/projects/hibernate/browse/HHH-1660
  http://opensource.atlassian.com/projects/hibernate/browse/HHH-1668

Began seeing this 3.1.1 and is also in TRUNK.

URL: http://anonhibernate.labs.jboss.com/trunk/Hibernate3
Revision: 10123
HQL dialect.

The testcase attached to HHH-1401 still fails:

Testcase: testNoExtraUpdatesOnMerge took 2.586 sec
        FAILED
Version was incremented although we did nothing
junit.framework.AssertionFailedError: Version was incremented although
we did nothing
        at
org.hibernate.test.hhh1401.HHH1401Test.testNoExtraUpdatesOnMerge(HHH1401Test.java:48)
        at org.hibernate.test.TestCase.runTest(TestCase.java:162)
        at org.hibernate.test.TestCase.runBare(TestCase.java:401)

These standard tests also failed. Don't know if there is any
correlation, though OptimisticLockTest seems promising. Log attached to
HHH-1401.
