It seems that it is allowed, but you're discouraged from using it because
you're potentially going to conflict with the inner class stuff.  From JLS
3.8:

	The Java letters include uppercase and lowercase ASCII Latin letters A-Z
	(\u0041-\u005a), and a-z (\u0061-\u007a), and, for historical reasons, the
	ASCII underscore (_, or \u005f) and dollar sign ($, or \u0024). The $
	character should be used only in mechanically generated Java code or,
	rarely, to access preexisting names on legacy systems.

If you're allowed to use it "rarely", then you're allowed to use it...
