/**
 * 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.
