TYPO3 Core

Use Case: I am uploading a file and want to create a file reference to that file, to add it to my model.

Code:

$folder = ResourceFactory::getInstance()->retrieveFileOrFolderObject($folderPath);
$movedFile = $folder->addFile($attachment['tmp_name'], hash_file('md5', $attachment['tmp_name']), DuplicationBehavior::RENAME);

$fileReference = $objectManager->get(TYPO3\CMS\Extbase\Domain\Model\FileReference::class);
$fileReference->setOriginalResource($movedFile);

Exception:

Call to undefined method TYPO3\CMS\Core\Resource\File::getOriginalFile()

Reason:
That is because the requested \TYPO3\CMS\Core\Resource\ResourceInterface (which does not implement method getOriginalFile()) is implemented by \TYPO3\CMS\Core\Resource\FileReference (which is probably expected), aswell as \TYPO3\CMS\Core\Resource\File
The breaking commit is https://forge.typo3.org/projects/typo3cms-core/repository/revisions/159fd37d509e00983a4348a2e860b3579f5f1b5b

Suggested Solutions:
I see 3 possible solutions for the TYPO3\CMS\Extbase\Domain\Model\FileReference::setOriginalResource() method:

1. It requires \TYPO3\CMS\Core\Resource\FileReference (like before, but I don't favour this solution as I cannot find an easy way to get an object of the ...\Resource\FileReference from a \TYPO3\CMS\Core\Resource\File)
2. It requires \TYPO3\CMS\Core\Resource\File (or \TYPO3\CMS\Core\Resource\AbstractFile) and calls "getUid()" directly
3. It requires \TYPO3\CMS\Extbase\Domain\Model\File (this would be package compliant, and you can easily get an object of the required class from \TYPO3\CMS\Core\Resource\File)
