Deprecation Message

[iAdil]

User Deprecated: Method "Symfony\Component\HttpKernel\Bundle\Bundle::boot()" might add "void" as a native return type declaration in the future. Do the same in child class "Craue\FormFlowBundle\CraueFormFlowBundle" now to avoid errors or add an explicit @return annotation to suppress this message.

Is this still an issue? Because it doesn't occur while running tests.
