I think you'd be better off using a Posix path for org-plantuml-jar-path so that 
(file-exists-p org-plantuml-jar-path) will find the file.  Then, since java is a 
Windows program, you'd have to patch the elisp sources to convert the Posix path 
to a Windows path (via 'cygpath -w') in the call to java.

I can probably do this at some point and send the patch upstream, but I'm busy 
with other things at the moment and won't be able to get to it for a while.
