I have some test code written using Scalatest which among things runs
akka-http client code to make requests against an HTTP service.
To test some error scenarios I use a URL that is incorrect, i.e. does not
offer the resource I expect to access. If the URL contains a hostname that
is unresolvable I get the failure shown below in initiating an Actor that
is apparently part of SimpleDnsManager.
If I provide a URL that is resolvable the failure does not occur.
I have checked the config for the ActorSystem that my test code is using
and it does seem to include an entry for akka.actor.deployment.router.
Anybody else seen this? I think I can boil this down to an easily
reproducible case and will do so if it helps fix a problem.
