        preg_match('/\@var ((?:(?:[\w|\\\\])+(?:\[\])?)+)/', $docComment, $matches);

It seems like $docComment can also be of type true; however, parameter $subject of preg_match() does only seem to accept string, maybe add an additional type check?

        if (!count($matches)) {
            $type->setNullable(true);

            return $type;
        }

        $varDocComment = end($matches);

        $resolver = new VarTypeResolver($this->reflection);
        $types = $resolver->resolve($varDocComment);
        $type->setTypes($types);
        $type->setArrayTypes(str_replace('[]', '', $types));
        $type->setHasType(true);
        $type->setNullable(strpos($varDocComment, 'null') !== false);

        return $type;
    }
