Hi,
We have a pretty straight forward ServerInterceptor implementation that
seems to randomly throw an IllegalStateException from its onHalfClose
method, which is simply calling the original ServerCall.Listener (from
next.startCall(...)) - the server then gets a CANCELLED result from the
client, and the connection (long term bidi stream) is then lost.
What could be causing this? Is there a way to get more info from the logs?
Thanks,
- Matt
Btw, this is the exception we get from gRPC in the logs
(grpc-netty-shadeddep-4.0.0-SNAPSHOT
is just a shaded dep around netty):
