It sounds like, to be able to mix interpreted and natively
compiled code at runtime, you need to have compiled your .jars
with the -findirect-dispatch option, right?
If so, why isn't -findirect-dispatch simply the default
compilation mode?

Right -- since the Java runtime should be smart enough to use
the lib as long as the signatures of the methods _it wants to
use_ match up, correct?
What does it mean to compile code with the "old style 'C++ ABI'"?
(Is that referred to as the "standard ABI"?) Does that just simply
mean to *not* use the -findirect-dispatch option?
Thanks,
