You're missing a Changelog and emacs-p might better be called cygwin-p.

More to the point: I don't think Org should care about such system
idiosyncrasies at all.  Instead you might use a wrapper script for
Cygwin that converts the arguments and then calls the native Windows
java executable.

If there's anything to do on the Org side then removing the still
hardcoded call of "java".
