Play client instrumentation throws exception

[rtfpessoa]

We are debugging a case where it seems like invoking this line https://github.com/kamon-io/Kamon/blob/master/instrumentation/kamon-play/src/main/scala/kamon/instrumentation/play/PlayClientInstrumentation.scala#L82
fails with this stacktrace:

Any ideas why this can happen?
(It might be a bad url from our client that happens to work, investigating now)
The code doing the client call has this deps https://mvnrepository.com/artifact/com.codacy/bitbucket-scala-client_playjson27_2.12/14.0.0

Also, is there a way to make Kamon fail without crashing the call?

EDIT: Seems like the real problem was an invalid URLs but still I would like to see how we can make Kamon instrumentation independent from the execution.

Anyone has suggestions?
