Do not be distracted by the complaint about SilverBullet.jar.
That is a normal part of this test. This particular sighting is
about the "exitValue = 134" which indicates that the target
process died due to a signal.

Update: Since the last line in the test's output is:

     - Test: VirtualMachine.list

I'm wondering if that's where the signal arrived.
