Any #java heads able to help here? My java is pretty limited. There has been work in the UpgradeProtocol method recently. This is the code that upgrades http 1.1 connections to http2 connections in #ApacheTomcat. I am trying to test a fix in stream handling, but I can't get the application to work. :/

```
