The completion function that does this is called _value in the Base
subdirectory, but it's written on the assumption that you have a real
parameter whose value you are altering.  The bit you're interested in is
the stuff with

  compset -P '*:'                   # strip stuff up to last :
  compset -S ':*'                   # strip stuff after next colon
  _default -r '\-\n\t /:' "$@"      # do default completion on this
                                    # -r is passed to compadd, see zshcompwid

You probably want to decant that into another function and use _arguments
to call this where you need it.

In fact, in this particular case I rather think you need the tweak to _java
in the patch at the bottom.

Yes, I'd forgotten I didn't have that set.
