Related, as part of this PR it might be needed to do a pass on the man pages, to make sure they are in sync -- I see for instance this:

       -nowarn
              Disables warning messages. This option operates the same as the -Xlint:none option.

Which would no longer be valid after this change. E.g.


javac -Xlint:none -Xlint:serial

is not the same as:

javac -nowarn -Xlint:serial
