A couple of things: 1) MyInterface.class could actually be MyAbstractClass.class 2) The instance returned by GWT.create is not necessarily stateless. So, even though both objects are equal upon creation, you can manipulate them afterward. As a result, you don't want both calls to GWT.create to return the same instance (unless its meant to be a Singleton). 3) Nothing guarantees that the objects are actually equal upon creation: static information could be used to initialize them (i.e. random)
