Comment 1 John Arthorne CLA 2010-07-02 11:34:23 EDT 
Min, can you take a look at this test? We haven't changed anything since 3.6.0 but it failed twice in a row now. It could just be a bad test.
Comment 2 DJ Houghton CLA 2010-07-08 09:32:44 EDT 
Note this also failed this week in the maintenance build M20100707-1005 and the nightly build N20100707-2000.
Comment 3 John Arthorne CLA 2010-07-19 17:57:51 EDT 
This is a faulty condition in the test. It is asserting that no other jobs run during the test. However, a completely unrelated job could be run by the platform, the test framework, etc, that would cause the condition to fail. I suspect some recent change elsewhere in the platform or test infrastructure cased this to start failing. It should instead only assert that the specific jobs in the test are only run the expected number of times.
