Can I deploy Retina with any JAVA version at all?
Taken from the instructions for how to modify Eclipse’s plist to get retina display. I can verify, this works. Perhaps something similar can be done with your app, assuming that the Mac version has a plist.

Do "Show package contents" on the Eclipse.app.
Edit Contents/Info.plist.
Just above

&lt;/dict&gt;
&lt;/plist&gt;

Place this:

&lt;key&gt;NSHighResolutionCapable&lt;/key&gt;
&lt;true/&gt;


Following were instructions on how to clear the cached version, but in a development environment while you are creating your apps, they are probably not useful.
