Subject [jira] Created: (HARMONY-3235) [drlvm][thread manager] smoke test gc.ThreadSuspension hangs from time to time on SUSE9 Linux x86 and x86_64

[drlvm][thread manager] smoke test gc.ThreadSuspension hangs from time to time on SUSE9 Linux
x86 and x86_64
------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-3235
                 URL: https://issues.apache.org/jira/browse/HARMONY-3235
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Elena Semukhina


The test hangs intermittently and should be run in the loop as follows:

 test=gc.ThreadSuspension; while true; do $DRLVM -cp <calsspath> $test; echo $i $test;
i=$[i+1]; done

Sometimes the test fails and then hangs:

-- starting unsuspendable computation --
-- starting suspendable computation --
forcing gc after 1 s delay
FAIL
gc completed

Please see stack traces in gc_ThreadSuspension_fail_x86_64.txt attachment for the above hang
on x86_64.

Sometimes it passes and hangs:

gc.ThreadSuspension
-- starting suspendable computation --
-- starting unsuspendable computation --
forcing gc after 1 s delay
gc completed
PASS

Please see stack traces in gc_ThreadSuspension_pass_x86.txt attachment for the hang on x86.
