What version of gRPC-Java are you using?

1.40.1

What is your environment?

openJdk-11 on ubuntu

What did you expect to see?

in case of bi-di methods (and probably also streaming-client-unary-server), when a client calls for example requestObserver.onError(Status.INTERNAL.withDescription("desc").asException()); the server should receive all messages scheduled for transfer by the client (with requestObserver.onNext(...)) prior to the call to requestObserver.onError(...). After that the server should receive a call to onError(...) with a Status(Runtime)Exception with identical status code (INTERNAL) and description ("desc") .

What did you see instead?

results of clients calling requestObserver.onError(...) are the same as if the call was cancelled: most recent request messages don't get transferred to the server and whatever status and description the client sets, the server always receives Status.CANCELLED and "client cancelled" description.

NOTE: It is possible, that this behavior is intended, but if so, it should be documented in onError(...)'s javadoc.

Steps to reproduce the bug

start a bi-di call on the client side, send some requests, call requestObserver.onError(Status.INTERNAL.withDescription("desc").asException());
