It's not possible to define a Java method that isn't declared in the
corresponding java .class file.  As a consequence of that, every
argument to that method must be well-defined from a Java point of
view.  So, you can't have a native method that takes a void*, for
example.  However, you can define a C++ wrapper class with a data
member which refers to the Java class.
