   Dropped the piece of code         /**

                   int valCnt = g.getFieldRepetitionCount(field);
   
                   Type fieldType = g.getType().getType(field);
                   String fieldName = fieldType.getName();
   
                   for (int idx = 0; idx < valCnt; idx++) {
                       if (fieldType.isPrimitive())
                           System.out.println(fieldName + " " +
