>> During the review of JDK-8272914 that added hotspot:tier{2,3} groups, @iignatev suggested to create tier4 groups that capture all tests not in tiers{1,2,3}. I have excluded `vmTestbase` and `hotspot:tier4,` because they take 10+ hours on my highly parallel machine. I have also excluded `applications` from `hotspot:tier4`, because they require test dependencies (e.g. jcstress).

Then you probably need to skip "printer" tests as well. BTW it will be really good somehow to execute headless tests in tier4 concurrently, and run the headful tests in tier5 sequentially.
