Scala Tracker problem when running inside Docker container

Here's the error:

I have seen it in stderr while it didn't have any impact on actual tracker's work or shutdown.

Created ticket to explore snowplow/snowplow-scala-tracker#48, but I think it would be better to solve it via snowplow/snowplow-scala-tracker#46

Will be solved by #57
