> We either need to make the server throw UnsupportedOperationException, or
> make the client to handle IllegalArgumentException. For backward
> compatibility and easier operation in the field, the latter is preferred.
> But we'd better understand why IllegalArgumentException is thrown instead of
> UnsupportedOperationException is thrown.
> The correct way to do is: check if the operation is supported, and throw the
> UnsurportedOperationExcetion if not; then check if parameter is legal, throw
> IllegalArgumentException is it's not legal. We can do that fix as follow-up
> of this jira.
