Note that the default javafinalize typemap must contain the full implementation of the finalize method.
Any customization to this typemap must still declare a java finalize method with the correct signature.
Note also that the name of the generated "delete" method may be affected by <tt>javadestruct</tt> and <tt>javadestruct_derived</tt> typemaps.
Below shows an example modifying the finalizer, assuming the <tt>delete</tt> method has been renamed to <tt>swig_delete</tt>.
