Seems to me that this is a RuntimeException then. Only an application
that is being written for Classpath will be able to take alternative
action if core functionality is missing. Any other application will
just have to throw up its hands.

It should *NOT* be a subclass of an existing exception type that has
well defined semantics and is likely to be caught in general
applications - like UnsupportedOperationException. I agree with Jeroen
that not being implemented when it should be, is quite distinct from
not supporting an optional operation.
