The test 'test/hotspot/jtreg/compiler/vectorapi/VectorRebracket128Test.java' only cantains a test 'VectorRebracket128Test.java#Z', thus 'compiler/vectorapi/VectorRebracket128Test.java#Z' should equivalence to 'compiler/vectorapi/VectorRebracket128Test.java'
But the follow command sitll select the test 'compiler/vectorapi/VectorRebracket128Test.java', the expectd result should be non tests found.
