Here's are snippets from the log file:

The test timed out and also exited with "exitValue = 134".
I suspect that the "exitValue = 134" is from JTREG aborting
the test after the timeout.

Based on other Scimark.java failures in the bug database,
I'm wondering if this timeout is due to a timeout in getting
something the test needs from artifactory.



The problem is in Scimark. It runs some testing and exits when it takes more than 2 seconds. It doubles the number of iterations for each attempt. However, MacOSX Aarch64 is so fast that it hits 'int' limit and is set to 0 causing an infinite loop.

The fix would be something like:

The main problem is that Scimark is not maintained and it is unclear where to fix it. Might be the best would be to remove it.
