Hi. As you see I used jtds driver for this one. It doesn't support setting the transaction isolation level to snapshot, but I tuned the database this way: ALTER DATABASE cruisecontrol SET ALLOW_SNAPSHOT_ISOLATION ON; ALTER DATABASE cruisecontrol SET READ_COMMITTED_SNAPSHOT ON; This should set the default isolation level to snapshot. When I runned the tests with the MS jdbc driver I got one more error than with the jdts driver. It is org.hibernate.test.legacy.MasterDetailTest.testCachedCollectionRefresh. But I'm not sure in the results as the cruesecintrol builds give half the errors of these I've got from the mentioned tests. So to conclude see if you see the results consistent with your local tests. I'll modify the build if you do not like the jtds driver or something else.
