@lmesnik There are failures with `make test TEST=vmTestbase/ JTREG=TEST_THREAD_FACTORY=Virtual` even without the change. And it is worse as the tests are flaky, so it is hard to compare with and without the change. 

Below are the test results `without` the change for 3 runs:


                   TEST                           TOTAL   PASS   FAIL   ERROR    SKIP   
jtreg:test/hotspot/jtreg/vmTestbase                3056   2990    17     4        45 
jtreg:test/hotspot/jtreg/vmTestbase                3059   2991    18     6        44
jtreg:test/hotspot/jtreg/vmTestbase                3062   2996    17     4        45
