In other tests we use `@requires vm.continuations` to ensure the test is only selected when the VM has the support. You are looking to skip a small subset of the j.u.concurrent tests so I see how you got here. It could use the WB API to filter on whether VMContinuations is true or false but that would be disruptive to the test in that it would need setup and run with -XX:+WhiteBoxAPI. As a short term "fix" then using !Platform.isS390x() should be okay (this is preferred to use the os.name property).
