Hi Shura, Thanks for doing it and it’s good to see the unnecessary dependency to java.management eliminated.
The new jdk.testlibrary.management package name is fine. It’s okay to keep the class name InputArguments as Jaroslav suggests and it’s easier to tell what this class is about. There is a copy of ProcessTools and InputArguments in the hotspot repository under hotspot/test/testlibrary/jdk/test/lib/ Are we planning to remove this duplicated copy? If not, same patch should be applied to those copy. It’s fine to separate this and push the hotspot test library change via hotspot-rt repo. Christian can probably sponsor the patch for you. I’ll sponsor the jdk change and push it to jdk9/dev once you send me an updated patch.
