I have seen that before. The way the crdt types work you insert via a merge method. Because we are doing custom serialization sre CrdtModule sometimes empty objects can throw that. We need better handling and logginf for that type of issue. I believe that comes from the first class which takes objects off the wire. -- Sorry this was sent from mobile.
