      I'm getting the following couple of lines quite a lot in my running Jenkins log

      Aug 20, 2018 10:32:29 AM INFO com.squareup.okhttp.internal.Platform$JdkWithJettyBootPlatform getSelectedProtocolALPN callback dropped: SPDY and HTTP/2 are disabled. Is alpn-boot on the boot class path?

Is alpn-boot on the boot class path?

      Any ideas what does that line trying to say?
