stephen mallette commented on TINKERPOP3-733:
---------------------------------------------

So I did have tests for bad serialization that occurred server-side.  Those exceptions properly report in the client.  

It wasn't clear to me the other day or today when i read this that the problem is that if the client-side experiences the serialization error - i didn't have tests for that scenario.  I assume that your workaround involved registering a custom {{MessageSerializer}} - if so, then that is the solution.  We probably have zero documentation on that anywhere - so that's yet another issue related to this.

> I ran into this issue trying to use titan 0.9.0-M2 with gremlin-server 3.0.0.M9-incubator.  Titan was returning a serialized RelationIdentifier which understandably could not be deserialized on the client side using the driver.  I have managed to work around this by using the IoRegistry, however the SerializationException thrown in GryoMessageSerializerV1d0.deserializeResponse() does not bubble back up to the CompletableFuture<ResultSet> returned from the Client.submitAsync() nor the CompletableFuture<List<Result> returned from ResultSet.all().  A warning is logged in DefaultChannelPipeline.exceptionCaught(), but that is as far as it goes.  Or am I missing something?
