> The predicatesIntoViews test (part of the derbylang suite) fails when running 
> the tests on a busy/slow system, but they pass when I run them on my fast 
> Windows box.
> It appears that the failure could be due to different optimizations being 
> performed due to the difference in speed of the machines.  This needs to be 
> confirmed that it is the case of the test failure.  I will attach the test 
> summary to this issue.
> I also noticed that the test report said 0% fail even though one test failed. 
> All derbylang tests passed on Windows XP. 
> Thanks,
