Contao 4.6 private service issue

[MicioMax]

On Contao4.6, I get this error :

The "phpbb_bridge.connector" service or alias has been removed or inlined when the container was compiled
solved patching "/src/Resources/config/services.yml" from

services:
    phpbb_bridge.connector:
        class: Ctsmedia\Phpbb\BridgeBundle\PhpBB\Connector
        arguments:
            - "@database_connection"
    phpbb_bridge.event_listener.contao_member_listener:
        class: Ctsmedia\Phpbb\BridgeBundle\EventListener\ContaoMemberListener
        public: true
        arguments:
          - "@phpbb_bridge.connector"
          - "@monolog.logger.contao"

to

services:
    phpbb_bridge.connector:
        class: Ctsmedia\Phpbb\BridgeBundle\PhpBB\Connector
        public: true
        arguments:
            - "@database_connection"
    phpbb_bridge.event_listener.contao_member_listener:
        class: Ctsmedia\Phpbb\BridgeBundle\EventListener\ContaoMemberListener
        public: true
        arguments:
          - "@phpbb_bridge.connector"
          - "@monolog.logger.contao"

So, made the 'phpbb_bridge.connector' service public.
This is a quick and dirty solution, it should be solved by dependency injection, but that's beyond my skills.
