A number of hotspot test ignore flags given externally. Running such tests in multiple VM configurations makes no sense (flags are ignored).
To reduce test execution time such tests could be labeled with the keyword "noflags", it will help to tune a test execution system to recognize them and avoid unnecessary runs.

List hotspot tests which are potentially "selfish":
