No Marshaller registered for RebalancingStatus enum class alongside Prometheus ------------------------------------------------------------------------------- Key: ISPN-12253 URL: https://issues.redhat.com/browse/ISPN-12253 Project: Infinispan Issue Type: Bug Affects Versions: 10.1.8.Final Reporter: Roni Polus Priority: Major Hello,  We encountered a very strange issue running infinispan with two instances of our application that connect to the same cluster. Once Prometheus is ran along with the other instances, it caused the following error.
