Deprecation message in Collector using Symfony 3.4

Q	A
Bug?	no
New Feature?	no
Version	1.7.1

Hi!! This deprecation message appear using Symfony 3.4 beta 2
User Deprecated: Implementing "Symfony\Component\HttpKernel\DataCollector\DataCollectorInterface" without the "reset()" method is deprecated since version 3.4 and will be unsupported in 4.0 for class "Http\HttplugBundle\Collector\Collector".

Adding a reset method in Http\HttplugBundle\Collector\Collector it's enough, but IDK what content must have

public function reset()
{
    return;
}

Regards
