Absolutely nothing to go on:

----------System.out:(2/128)----------
NativeTestHelper::DEFAULT_RANDOM.seed = -997602716
Re-run with '-DNativeTestHelper.DEFAULT_RANDOM.seed=-997602716' to reproduce
----------System.err:(0/0)----------
----------rerun:(40/6765)*----------
...
result: Failed. Unexpected exit from test [exit code: 134]

Only odd thing is that dmesg shows:
