Descriptions

It is expected that the onError method of StreamObserver can pass through custom exceptions to the Consumer. Currently, the onError method in ServerCallToObserverAdapter is as follows:

public void onError(Throwable throwable) {
    final TriRpcStatus status = TriRpcStatus.getStatus(throwable);
    onCompleted(status);
}

This ultimately returns a StatusRpcException.
