### Describe the bug, including details regarding any error messages, version, and platform. In flight producer , User is throwing StatusRuntimeException having metadata with custom error message from the implementation class of [FlightServerMiddleware.onCallStarted](https://github.com/apache/arrow/blob/main/java/flight/flight-core/src/main/java/org/apache/arrow/flight/FlightServerMiddleware.java#L52) , eg: ` Metadata trailers=new Metadata(); trailers.put(Metadata.key.of("custom_msg",Metadata.ASCII_STRING_MARSHALLER),"custom error msg"); throw StatusUtils.fromGrpcRuntimeException(new StatusRuntimeException(Status.UNAUTHENTICATED,trailers) ); ` But this is getting override in in catch block of [ServerInterceptorAdapter.interceptCall](https://github.com/apache/arrow/blob/ded148c2ef5dd441a3b6ab9496d0ed0aeb940f71/java/flight/flight-core/src/main/java/org/apache/arrow/flight/grpc/ServerInterceptorAdapter.java#L104) , Because of this at flight client side user is not able to propagate meaning error message , Only correct status is received at client side . Expectation : Metadata from FlightRuntimeException should be used while closing the call . [ServerInterceptorAdapter.interceptCall](https://github.com/apache/arrow/blob/ded148c2ef5dd441a3b6ab9496d0ed0aeb940f71/java/flight/flight-core/src/main/java/org/apache/arrow/flight/grpc/ServerInterceptorAdapter.java#L104) ` call.close(StatusUtils.toGrpcStatus(e.status()), e.status().metadata()); ` ### Component(s) FlightRPC, Java -- This is an automated message from the Apache Git Service.
