As for the original (03) webrev - I wouldn't rename InputArguments into 
RuntimeMXBeanTool. The new name really does not reflect the 
functionality the class actually provides. IMO, you can keep the 
original class name and still move it to jdk.testlibrary.management.

As for the last (04) webrev - this change doesn't seem to be related to 
the issue. It is just a cleanup of a potential NPE. I would suggest 
either updating the issue summary to be more generic or address the NPE 
in a separate changeset.

Another possibility I have considered is “ext” or “extended” subpackage, which would have all the classes which depend on anything but java.base. With “ext” there would be no way to keep the desired granularity with the test modules dependencies.
