Hi Naoto,
A couple of questions:
- Are there any scenarios where invoking setProperty will not override the
command line setting ?
- Did you consider an `@ImplNote` for your clarification given the behavior
"might" be different in other implementations (I am not sure myself) and is
implementation defined?
