----------System.err:(3/38)----------

JavaTest Message: Test complete.

result: Error. Agent error: java.lang.Exception: Agent 7 timed out with a timeout of 1200 seconds; check console log for any additional details


Based on "JavaTest Message: Test complete.", it looks like the
test passed, but then timed out. Normally when a test times out
in the middle of a run, you have a line like this:

Timeout refired 1200 times

and that line appears in "#section:driver" so it looks like this
test passed while the timeout handler was running. The other
three sub-test failures have the same markers.

I think this test might need a longer timeout value.

The test task's JVM args are:
-XX:+CreateCoredumpOnCrash -ea -esa -XX:CompileThreshold=100 -XX:+UnlockExperimentalVMOptions -server -XX:+TieredCompilation -XX:+VerifyOops
