I do this now. But if I wish to change bytecode
this will not help.
For example, currently I changed class signature
to understand valid kiev & pizza signatures, like
Lkiev/stdlib/List;<Akiev/stdlib/List$A;> for kiev
and Lpizza/util/List;<AA;> for pizza. For example,
op_new, or_instanceof bytecodes and others
will crash for normal JVM... The class will not be
I mean, I did (and Martin Oderskiy too) all possible
with additional attributes, and kiev (as well as pizza) are
compatible with Sun's JVM... But I wish
to add _full_ support for extensions. This mean
the change not only in the set of bytecode, but
change class constants and so on. New bytecode
will not be compatible with Sun's specification.
