Submitting a JEP

[Brian Goetz]

The proposal is a bad fit for the assertion facility, since the 
assertion facility is designed to be disabled, and what you want is 
something that can't be disabled.

But here's an alternative:

     throw new UnreachableAssertionException("why");

This doesn't need a language feature.  It doesn't even need a special 
exception class:

     throw new AssertionError("Unreachable: blah blah");

Adding language features has a significant cost; we prefer to spend that 
where there are not practical alternatives.
