The following test timed out in the JDK16 CI:

The test specifies "main/timeout=60" but must have been
invoked with a timeoutFactor of 10 since the total timeout
value was 600 seconds/10 minutes. Including the timeout
handle, the test executed for 702.968 second.

I don't see any indicators in the log file as to what went wrong.
