title: Excluding methods from GWT modules
body: <p>I have a class that I want to include in a GWT module.  Unfortunately, it has a method that has functionality unsupported by GWT (it uses Class.isInstance in case you're curious).  I do not use this method in my GWT application, but other non-GWT apps use this method, so I cannot simply remove it.  Is there a way to exclude this method in my module definition?  Perhaps an annotation on the method can do this?</p>
