     In situations like this, I think

	throw new AssertionError("BUG!", ign);

is marginally better in that it preserves all the information from
the "cannot happen" exception instead of only its message text.  (If
you ever catch a "cannot happen" exception something very odd must
have happened, and if something *that* odd happens you'll be glad of
every possible clue ...)

     Yes.  Sometimes, anyhow.
