TYPO3 Core

Hi,

while trying to install TYPO3 9.2/9.3 the doc comment parser throws an exception. There's a try in typo3/sysext/extbase/Classes/Reflection/ClassSchema.php on line 305 which causes the error because the cascade annotation does not exist.

try {
    $cascadeAnnotationValues = $docCommentParser->getTagValues('cascade');
    $this->properties[$propertyName]['annotations']['cascade'] = $cascadeAnnotationValues[0];
} catch (\Exception $e) {
}
