Review Comment:
> > Dont think we should return `false` right after validator.test is
`false` as it wont go into `chainedClassifier` check. Instead, we should return
false at the line 55.
> > Good comment, PR was updated. A little difference, `chainedClassifier`
check includes `false` and `true`, It seems that new "return false" is not
needed.
If we carry on to `chainedClassifier` check, the result is being `false`,
isn't it? so if there is nothing to check from `chainedClassifier`
(`chainedClassifier` is `null`), shouldn't we return `false`?
