Looks good, just a small question about the name of the test

test/hotspot/jtreg/testlibrary_tests/verify/tests/TestVerifyIncubatorVector.java line 44:

I have doubts about leaving the "Incubator" name in the test class name as it's temporary. Are you going to refactor the class name when API is not incubator any more? Maybe `TestVerifyVectorAPI` instead?
