/**
 * This class reflects a single Java constructor into the JavaScript
 * environment.  It satisfies a request for an overloaded constructor,
 * as introduced in LiveConnect 3.
 * All NativeJavaConstructors behave as JSRef `bound' methods, in that they
 * always construct the same NativeJavaClass regardless of any reparenting
 * that may occur.
