The information in this section is only of interest to those that need
to read or modify code that used library(jasper) before
SICStus 3.8.5.
A different way of doing method call and creating objects was used in
versions of library(jasper) earlier than SICStus 3.8.5. Use of
these facilities are strongly discouraged although they are still
available in the interest of backward compatibility.
The old method call predicates are jasper_call_static/6 and
jasper_call_instance/6 as well as the old way of calling
jasper_new_object/5.
