Deprecation in UnderscoreNamingStrategy

[garak]

I use naming_strategy: doctrine.orm.naming_strategy.underscore in my Symfony project config.
I'm getting the following deprecation:

Creating Doctrine\ORM\Mapping\UnderscoreNamingStrategy without making it number aware is deprecated and will be removed in Doctrine ORM 3.0.

I tried to look into code to see if I can avoid it using some config, but it couldn't find anything

Required versions:
"doctrine/doctrine-bundle": "^2.0@beta",
"doctrine/orm": "^2.7",

See #1059: in the meantime you can define your own service and use that in your config. This will be available in 1.12.x. We'll be keeping the underscore strategy around in 2.0 as well until the bundle supports ORM 3.0.

You can replace this with
naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware
