I'm wondering about SocketImpl.create(boolean). We can't deprecate this method but maybe we should add a note to its API docs to say that Socket constructors to create a datagram socket is deprecated. If we do remove the constructors then I think SocketImpl.create(boolean) will be changed to throw UOE if the value of the parameter is false.
