Snapping Java Swing applications

[Reinhard Pointner]

--devmode didn't make a difference. In --devmode, is it supposed to be able
to load libraries and fonts from the system?

I guess there's just some odd dependencies missing that are not declared
cause they're always just there on normal systems. I'll look into the
OpenJDK and see if I can find anything.
