The Java bytecode is intentionally _not_ a "universal machine
language". I suppose you could implement full C, including pointer
arithmetic, in it by adding a package of "unsafe conversions", but
then you're losing the "powerful benefits" of safety and machine-
independent behavior.


On the other hand, many "safe" languages could be translated into
clean Java with modest performance losses compared to native code, and
preserving the powerful benefits of safety, machine-independent
behavior, and machine-independent representation.
