             Summary: Test failures under Java 7 caused by different order of tests
                 Key: JCS-114
                 URL: https://issues.apache.org/jira/browse/JCS-114
             Project: Commons JCS
          Issue Type: Bug
            Reporter: Sebb


ON Java 7 under WinXP I get several test failures. These do not occur with Java 6. The failures are:

{code}
 org.apache.commons.jcs.access.SystemPropertyUnitTest#testSystemPropertyInValueDelimiter AssertionFailedError
 org.apache.commons.jcs.auxiliary.disk.jdbc.JDBCDiskCachePoolAccessManagerUnitTest#testConfigurePoolAccessAttributes_Simple ComparisonFailure
 org.apache.commons.jcs.engine.memory.lru.LHMLRUMemoryCacheUnitTest#testGetStatsThroughHub AssertionFailedError
 org.apache.commons.jcs.engine.SystemPropertyUsageUnitTest#testSystemPropertyUsage_inactive AssertionFailedError
 org.apache.commons.jcs.engine.SystemPropertyUsageUnitTest#testSystemPropertyUsage AssertionFailedError
{code}

AFAICT these failures occur because Java 7 runs tests in a different order from Java 6.

In each case, the test class has 2 tests.

Either the Unit tests are wrong - e.g. the second test relies on something set up by an earlier test, or the second test fails to clear up afterwards so causes a problem when the test order is reversed.

Otherwise there must be a problem in the code under test - e.g. the code caches a value that it should not.
