# Helpful things

## Purpose

Fixes `p.microbenchmark.it.HelloWorldBenchmark` when using akka-http-2 (ak-20-enc) and akka http1.1 encrypted (ak-11-enc)

## Background Context

`ak-20-enc` was failing with a `java.lang.ClassNotFoundException: akka.http.scaladsl.Http2` exception because of missing akka-http2-support jar.
`ak-11-enc` was failing with a `javax.net.ssl.SSLPeerUnverifiedException: Hostname localhost not verified:` which was solved by setting the a dumb `hostnameVerifier` in the OkHttp client
