title: Using gRPC with Vert.x, netty dependency issue
body: <p>I am trying to add a gRPC to one of our vert.x servers and running into some issues. Has anyone else tried running gRPC alongside vert.x? The first issue I am running into is due to a netty dependency version mismatch: Vert.x wants to use netty 4.0, while gRPC needs netty 4.1.</p>
  
  <p>Specifically, the issue I am running into is when netty 4.1.0-Beta5 is used I get a AbstractMethodError on a call to org.vertx.java.core.http.impl.AssembledFullHttpRequest.touch because that method is not implemented. AssembledFullHttpRequest implements the ReferenceCounted interface that netty provides, which added a touch method between versions 4.0 and 4.1.</p>
  
  <p>Any advice would be appreciated.</p>
  
  <p>I have also posted this question to the gRPC and Vert.x google groups.</p>
  
  <p>Thanks,
  Aaron</p>
