There are two kinds of compatibility.  Old programs continue to run on
new hardware or JVMs.  Is that Forward or Backward compatibility?  I
have heard people use both terms.

The other is new programs written carefully with new tools to avoid
using new features will run on old hardware and JVMs.

Is that Forward or Backward compatibility?  or something else?

IBM salesmen loved to talk about upward and downward compatibility. 
The IBM mainframers were very serious about ensuring even extremely
old code would continue to run, even if it took multiple layers of
emulation. 1410 emulation was still running in the 1990s, long after
1410 boxes lived only in museums.  Again, I am not sure what they
meant by the terms. I think they used them synonyms for "good" and
"reliable".

If there is a consensus, I will do a entry in the glossary on the
matter.
