print exception trace for failed tests as test completes with derby.tests.trace=true?

[Kathey Marsden]

I am dealing with a problem where I get a hang in the tests, but several 
tests error before the hang.
I was thinking it would be useful to print the exception trace for 
failed tests after printing the test if
derby.tests.trace=true.  Does anyone have objections to such a change? 
The traces would still print
in the summary at the end of the run.

Thanks
