TYPO3 Core

When the DI container is stale (e.g. missing classes, happens often during development), an exception is thrown and the DI container becomes unavailable. However, the thrown exception is attempted to be logged in the database which doesn't work anymore, as ConnectionPool->getOrderedConnectionDriverMiddlewareConfiguration() instantiates DriverMiddlewareService, which has additional dependencies. Since those cannot get loaded due to the missing container, a follow-up error is thrown, hiding the real issue.
