A solution to avoid performance degradation associated with load-object independence by arranging interface source code, particurlarly JNI source code, in a stylized form, and then preprocessing the stylized interface source code into a Virtual Machine ("VM") specific form. The stylized source code allows a preprocessor to identify and track field and method identifiers, and to match up the field and method uses with the specification of the field or method. The source code is stylized by substituting stylized variable names, each with a native element identifier, for non-stylized variables.
