Mike Matrigali updated DERBY-6286:
----------------------------------

    Description: 
There are atleast 4 occurences of these lock timeout exceptions. One of those 4 failures is for testCompressWhileScanning fixture and other 3 are for testDropWhileScanningThenDelete fixture. All these failures are with IBM jdk 1.7 or IBM jdk 1.6. The test failed on following dates
1)2012-04-21 - http://people.apache.org/~myrnavl/derby_test_results/v10_8/windows/testSummary-1328766.html - fixture testCompressWhileScanning
2)2012-05-16 - for some reason the public website(http://people.apache.org/~myrnavl/derby_test_results/v10_8/windows/testSummary-1339443.html) doesn't show the error but internal IBM run on that day shows following error - 1) testDropWhileScanningThenDelete(org.apache.derbyTesting.functionTests.tests.store.AutomaticIndexStatisticsTest)java.sql.SQLTransactionRollbackException: A lock could not be obtained within the time requested
3)2012-07-14 - http://people.apache.org/~myrnavl/derby_test_results/v10_8/windows/testSummary-1361618.html - fixture testDropWhileScanningThenDelete
4)2013-06-28 - http://people.apache.org/~myrnavl/derby_test_results/v10_8/windows/testSummary-1497975.html - fixture testDropWhileScanningThenDelete

There may have been more than these 4 failures but so far, I have been able to locate only these 4
