[keycloak-dev] Error loading KeycloakHotRodMarshallerFactory

Hello, I am facing an issue in regards to launching Keycloak 3.4 in Domain mode with an external Infinispan cluster. I following error is thrown: Caused by: java.lang.ClassNotFoundException: org.keycloak.cluster.infinispan.KeycloakHotRodMarshallerFactory from [Module "org.wildfly.clustering.service" from local module loader @7a0ac6e3 (finder: local module finder @71be98f5 (roots: /opt/jboss/keycloak-3.4.3.Final/modules,/opt/jboss/keycloak-3.4.3.Final/modules/system/layers/keycloak,/opt/jboss/keycloak-3.4.3.Final/modules/system/layers/base))] I don't get this error when using the standalone-ha mode. Did you test the Multi datacenter configurationh with the domain mode already? https://www.keycloak.org/docs/latest/server_installation/index.html#_doma... Guide Overview - Keycloak<https://www.keycloak.org/docs/latest/server_installation/inde... www.keycloak.org The purpose of this guide is to walk through the steps that need to be completed prior to booting up the Keycloak server for the first time. If you just want to test drive Keycloak, it pretty much runs out of the box with its own embedded and local-only database. Why would be the class KeycloakHotRodMarshallerFactory not correctly loaded in domain mode? I will keep searching but would be happy if some of you would have time to share their opinion on this. Thank you in advance for your direction.
