> This is a test-only change. ThreadAPI.testGetStackTrace2 tests the stack trace of a virtual thread that has started but has not executed it. The test currently attempts to saturate all carrier threads before starting a target thread. The test is not reliable and failed at least once with a debug build and -Xcomp. The test is changed to use a custom scheduler that discards the task so the thread doesn't execute. The resulting test is much simpler and removes 3s from the execution time.
