Breaking: #61821 - classFile option in makeInstanceService removed

See Issue #61821

Description

The option “classFile” in \TYPO3\CMS\Core\Utility\GeneralUtility\makeInstanceService() is removed. This should now be done by the respective ext_autoload.php of each extension.

Impact

Extension classes relying on the “classFile” registration for autoloading will not be loaded anymore.

Affected installations

A TYPO3 instance is affected if a 3rd party extension uses the removed class loading registration method.

Migration

Use the ext_autoload.php file to autoload the class.
