The inverse, where exclusiveAccess.dirs prevents tests in a directory/tree from running at the same time as other tests in that directory/tree also doesn't prevent tests in other locations from executing concurrently. Given the execution times, I wonder if you've looked at using the finer grain test groups and splitting the execution across a number of machines. Yes, it means combing results but I assume you'll this for high tiers anyway as the execution time goes up significantly beyond tier1. ------------- PR Comment: https://git.openjdk.org/jdk/pull/24229#issuecomment-2753896771
