if by "patch" you mean git-am/git-apply then I'm afraid i don't have any 
suggestions because i don't use those commands.  However, if you use 
git-push then have you thought about having a script on the local side 
that does something like this:

$ git checkout java-branch
(hack hack)
$ git add .
$ git commit
$ bash -v myscript  <--run your script
#!/bin/sh
# script to commit java-branch head to cpp-branch and push them both
git checkout cpp-branch &&
wait
git cherry-pick java-branch &&
wait
git push origin HEAD &&
wait
git checkout java-branch &&
wait
git push origin HEAD &&
wait
exit 0

of course, you need some error checking in there.  this is predicated on 
the assumption that the cherry-pick will not get any conflicts.  if it 
does get conflicts then you will have to resolve them manually and that 
is a big reason to do this on the local side instead of the remote side.
