The maximum likelihood estimate that is not normal

For most models the maximum likelihood estimator is asymptotically normal with variance set by the Fisher information. But consider i.i.d. observations X1,,XnX_1, \dots, X_n from Uniform(0,θ)(0, \theta), where the maximum likelihood estimator is the sample maximum θ^=X(n)\hat\theta = X_{(n)}.

Show that θ^\hat\theta is not asymptotically normal, find its convergence rate and limiting distribution, and explain why the usual theory fails.

This one is open-ended. Work it through, then check your reasoning against the full solution.
