Re: Dependeny on javax.swing

I agree that what GAE provides isn't a JRE, but the important question
is if we want FreeMarker to run on GAE (imagine it as a new target if
you want), regardless if it can be called "Java" or not. And of course
we do since Google is a really big dog, right? Surely the whole issue
is a PITA to fix but... do you really belive Google will eventually
fix these? /-:
