Exception is created but not thrown

[AppChecker]

Hello!

1. In method Collection::filterByProductType:

      if (!is_string($typeFilter) && !is_array($typeFilter)) {
            new \Magento\Framework\Exception\LocalizedException(__('The product type filter specified is incorrect.'));
        }

\Magento\Framework\Exception\LocalizedException is created but not thrown.
Is "throw" keyword missing?

2. In method AbstractProduct::getModel:

        try {
            $model = $this->_indexFactory->get($this->_indexType);
        } catch (\InvalidArgumentException $e) {
            new \Magento\Framework\Exception\LocalizedException(__('Index type is not valid'));
        }

\Magento\Framework\Exception\LocalizedException is created but not thrown.
