Looks good. I commented on two nits.

If you don't have a quick idea on how to fix `WARNING: JNI local refs: 921, exceeds capacity: 32`, you could open a bug for it (if there isn't one already) and right away exclude the test with reference to the new bug.
The alternative would be to filter out the local refs warning but then I guess this will be forgotten.
After all, either way is not perfect...

Add the current year to copyright.

Maybe better: "Launching app with debug agent shouldn't produce any jni warnings." ?
