Since we don't really verify the output, I don't think one would be needed.  The test was originally added when there was a safepointing lock around BytecodeTracer in JDK 7 and the Method* moved, so all the test did was verify that tracing bytecodes didn't crash.  With the concurrency I added, it did crash and found a bug that I fixed in BytecodeTracer::trace function.
