The note continues:

  Treating "file" as a special case is the minimum that will fix this
  problem.  If other protocols are required in a statically linked
  application they will need to be handled in the same way as "file".

I presumed that the "core" handler was done in this way because it
will definitly be required in a statically linked application.

No, not at all.  I'm suggesting we remove the special case for
creating core URLStreamHandlers.
