And if you want to put additional code, the best is to trap all return 
instructions
in visitInsn.

public void visitInsn(int opcode) {
   // trick all return opcodes are between IRETURN and RETURN
   if (opcode >= IRETURN && opcode <= RETURN) {
      // don't forget that the return value is already on top of the stack
      ...
   }
   super.visitInsn(opcode);
}
