Notes for binding_of_caller jruby support

	- Perhaps can get to it without any java code: https://gist.github.com/1680784
	- Interpreter only flags: https://github.com/quix/boc/blob/master/jext/boc/BocService.java

	Code sections that are relevant:
	- Kernel#binding: return RubyBinding.newBinding(context.runtime, context.currentBinding());

	- ThreadContext:
	- 1223 public Binding currentBinding(IRubyObject self) {
	- 1224 Frame frame = getCurrentFrame();
	- 1225 return new Binding(self, frame, frame.getVisibility(), getRubyClass(), getCurrentScope(), backtrace[backtraceIndex].clone());
