--------------------------------------

             Summary: store.AutomaticIndexStatisticsTest fails intermittently with 'A lock could not be obtained within the time requested' on 10.8 codeline
                 Key: DERBY-6286
                 URL: https://issues.apache.org/jira/browse/DERBY-6286
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.8.3.1
            Reporter: Mamta A. Satoor


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
