java.net.SocketException: Connection reset

See original GitHub issue

Summary

Often - but not always - I’m seeing this in the Stryker4S log:

04:09:27.238 [scala-execution-context-global-360] INFO  stryker4s.report.ConsoleReporter - Starting test-run 173...

I don’t exactly understand what is happening here, and why I’m seeing this message. From the message, I don’t know what to do either.

It seems that the last run (with Stryker 0.10) re-introduced those mutants. Let’s close this case for now…

I’m now on 0.10.0-RC2, and the dashboard is updated nightly. Haven’t tried with 0.10.0-RC3 recently, somehow ScalaSteward didn’t offer a pull request just yet 😉
