Message:

First stab at restoring runtime-class.
Supported: extending a Java class, implementing interfaces, defining methods
of up to 7 non-primitive arguments returning void or a non-primitive object.
Unsupported: everything else, including fields, constructors, annotations,
primitive arguments and return values, and the LispObject[] call convention
for functions with more than 8 arguments.
