Hi Jayaram,

This sounds like good progress. Now you know which tests that call this
method. I think the next step would be to find out what the queries look
like. Can you see that from the test logs? If not, maybe you can make
the method throw an exception so that the test stops once the method is
called. If we know what the queries look like, we may find a way to
tweak them so that they trigger the bug.
