If no user is allowed to catch this new error/exception, why are we going
to the bother of creating it in the first place??

If the only reason for creating the new exception is as a documentation 
aid, then a better approach would be to throw UnsupportedOperationException
with a stereotypical error message and or stereotypical javadoc description.

I think it is unreasonable to expect application developers to know
which features where unimplemented / implemented in which versions
of Classpath.  IMO, this far more awkward than catching an exception.
