 I think you dind't quite get how it works with MMtk. There are a few 
"magic" classes that receive special treatment from the compiler and 
translates method calls into pointer operations. This way MMtk can operate 
under the same condition of C code. 
 I'm not sure how did you relate interface calls with MMtk, as this is a 
non-issue. And with memory barriers, it's a problem all languages will have 
to face, be it Java, C or assembly.
   
But it might still be that C-implemented modules (particularly the
