Kathey Marsden updated DERBY-3110:
----------------------------------

    Attachment: derby-3110_stat2.txt
                derby-3110_diff2.txt

Here is a revised patch for this issue. The code patch remains the same. The test loads its
own policy file to allow for tracing. The new test NetworkServerControlApiTest only tests
tracing now but can be expanded to cover the other API calls.
