Steps to reproduce the bug
- Bump Netty version to 4.1.101.Final.
- Execute any test that sends a request and receives a response with trailers.
Additional details
The changeset #13603 uses headers.isEmpty() method. gprc-java has its custom implementation of Netty's Http2Headers interface, where they implement only size() but not isEmpty() method. Its parent AbstractHttp2Headers implements this method as throwing UnsupportedOperationException.
