title: Java, gRPC and Context propagation
body: <p>Does anyone have a working example of <strong>io.grpc.Context</strong> propagation between client (stub) and server using gRPC in java?</p>
  
  <p>My understanding is that it's not possible and I must use Metadata instead. Am I correct?</p>
  
  <p>Online I have found only examples using <em>Header</em> rather than <strong>Context</strong>.</p>
  
  <p>Thanks!</p>
