The C++ parsing code doesn't look complex:
https://trac.videolan.org/vlc/browser/trunk/modules/gui/skins2/parser/expr_evaluator.cpp

This is then used by:
https://trac.videolan.org/vlc/browser/trunk/modules/gui/skins2/parser/interpreter.cpp

I'm sure that you could pretty much cut and paste the parser in java.
You'll then need to simulate interpreter.cpp in the skin designer.
