Fixed version (ground truth):

        error=false;
        break;
      }
    }
    if (error) {
      if (targetType.isPrimitive()) {
        targetType=ReflectionUtils.getObjectClassOfPrimitve(targetType);
      }
 else {
        targetType=ReflectionUtils.getPrimitiveClassOfWrapper(targetType);
      }
      if (targetType != null) {
        for (        TargetType t : possibleTargets) {
