Digant Kumar commented on SUREFIRE-1386:
----------------------------------------
Hi [~tibor17],
It is possible that "Surefire is not waiting long enough for the forked VM and
assumes it to be dead", as mentioned in SUREFIRE-1302.
Lately I have also seen that coverage got dropped by ~5% (we run tests in
parallel, 12 jvms). This kind of behavior can also be explained with issue like
SUREFIRE-1302.
I do not have the dump right now, as build was re-triggered and rerun has
replaced the work-space. Will provide the dump when ever I see such issue again
next time.
