Java casts need be explicit only if they convert a one to a sign bit or if they
truncate one's.  Truncating zeroes remains (yeeuck) implicit e.g.

        final int i = 0x7F;
        byte b = i;

And the rules on how many sign-extension bits to add implicitly have changed
for the shift operators and for the ?: if-then-else operator.
