<snip>
test result: Error. Program `/scratch/opt/mach5/mesos/work_dir/jib-master/install/jdk12-jdk.100/linux-x64-debug.jdk/jdk-12/fastdebug/bin/java' timed out (timeout set to 1200000ms, elapsed time including timeout handling was 1667947ms).

So the System.err portion of the log indicates that the
test passed, but the end of the test indicates that it
timed out at 1667947ms
