Sometimes the intertyped method requires a bridge method alongside it. For example if the method 'N SomeI.m()' is put onto
an interface 'interface I' and then a concrete implementation is 'class C implements I' then the ITD
on the interface will be 'Number m()', whereas the ITD on the 'topmostimplementor' will be 'Float m()'. A bridge method needs
to be created in the topmostimplementor 'Number m()' that delegates to 'Float m()'
