ah right yeah. well that folder would be a helpful place as there is some mechanism to re-read the java font cache IIRC (I did this once on my PC) and that folder would be included AFAIK as the default.
I know almost zero Java but have noticed the method stub you refer to while fiddling. didn't have a play mate.
here's some resources (they don't contain your stuff AFAICT but helpful anyways to others...)
personal basis (check your version, future reader)
http://docs.oracle.com/javame/config...217/index.html
Some kindlet stuff: (always check your references are the right version)
https://kdk-javadocs.s3.amazonaws.co...w-summary.html
Sorry I can't help more mate.
If you do figure it out it would be great to know. Thanks.
