After running a Hot Rod server for a while, I get a NullPointerException in HotRodEncoder.getTopologyResponse(), how can I get around it?
This is a bug (see ISPN-669) in the Hot Rod code where we didn’t specifically set the topology cache to have no eviction and no expiration. So, if someone configured the default cache in the Infinispan configuration file for Hot Rod with expiration or eviction, the topology cache would end up having those capabilities and the topology view could after a while be removed from memory. To get around this issue either: • Avoid having expiration and eviction on for the default cache. • Or, make sure you create a namedCache for ‘___hotRodTopologyCache’ with sync replication, state transfer, no expiration and no eviction.
