That is just the point since they all have a vendor and no standard
things change under the cover all the time and there is nothing for them
to answer to.

So there is no "Java Standard" as you wrote, not even a defacto standard
among vendors (take a look at J++).

Just as an example (one of many possible) when Microsoft specified the
method ITypeInfo::GetRefTypeOfImplType they specified an Unsigned
Integer as an index. Yet since things have changed in the COM world (of
course this is not supposed to happen) you need to pass in a negative
index to get the TKIND_INTERFACE out of a TKIND_DISPATCH that is a dual
interface (something MS added after the original COM/OLE specs were
drawn up to support faster access to OLE objects from early binding
languages and tools.) Which means I have to write code to go against the
MS specs and bindings:

   -----------------------------
   -- Get_Interface_Reference --
   -----------------------------

   procedure Get_Interface_Reference(Source : in Object;
                                     Index  : Integer;
                                     In_To  : in out Object)
   is
      function To_UINT is
         new Ada.Unchecked_Conversion (Integer, Win32.UINT);
      
      Reference : aliased Win32.OleAuto.HREFTYPE;
   begin
      Check_HR(
        
Source.ITypeInfo_Pointer.lpVtbl.GetRefTypeOfImplType(Source.ITypeInfo_Pointer,
         To_UINT(Index),
         Reference'Unchecked_Access ) );

      Get_Reference(Source, Reference, In_To);

   end Get_Interface_Reference;
