Missing iterator() implementation in AbstractHttp2Headers #10837
Description
Hi,
This looks like a different flavor of an earlier issue. The iterator method used here seems to be unimplemented here
Is it possible to provide a fix or workaround for this?
What version of gRPC-Java are you using?
Using grpc-netty-1.30.2 with Netty 4.1.104.Final.
What is your environment?
Linux
What did you expect to see?
No failures on upgrade from Netty 4.1.100.Final
What did you see instead?
Crash with stack trace as below
