Before this, it was possible to pass an arbitrary string to the method,
and have no way of knowing about the problem. IllegalArgumentException
is derived from RuntimeException, which is explicitly documented to be
allowed at every interface method, signalling errors not covered by the
interface method specification, so this is not an API change.
