Hello. After updating to the latest kamon 2.1.5 I observed that a simple sbt test that has been running smoothly with kamon 2.14 is now broken and this is the error:

The issue here is that I left some dependencies unattended on the Play gRPC tests and that caused an entire Akka version to be shaded in the kamon-bundle. Fix coming in a minute.
