MessageSubscriberInterface deprecated in Symfony 6.2 and removed in 7

[mgrundkoetter]

In the HandlersLocatorFactory class, there is code which will cause an exception in Symfony 7+:

$messageHandlerClasses = $this->reflectionService
    ->getAllImplementationClassNamesForInterface(MessageSubscriberInterface::class);

foreach ($messageHandlerClasses as $messageHandlerClass) {
    foreach ($messageHandlerClass::getHandledMessages() as $messageName => $config) {
        if (! \is_array($config)) {
            throw new \InvalidArgumentException(
                'different from doctrine, we (currently) need subscribers to always have an option array'
            );
        }
        if (isset($config['bus']) && $config['bus'] !== $busName) {
            continue;
        }
        $handlerDescriptors[$messageName][] = new HandlerDescriptor(
            $this->objectManager->get($messageHandlerClass),
            $config
        );
    }
}

It can just be removed completely.
