Is it really necessary to add this into the open code base? Would this
not be more appropriate in whatever proprietary fork you use at Oracle?
'Commercial' is also the wrong word to use, as this is nothing
non-commercial about the rest of the OpenJDK code base. What you're
referring to are proprietary features which you're not releasing the
source code to.
