[keycloak-user] Unable to unmarshall bytes for CLIENT_CACHE_ENTRY_CREATED

[Nicolas Ocquidant]

Hi

This is my very simple UC to reproduce:

1. Start one Infinispan node with passivation=false and shared=true (I
don't think parameters are important here)
2. Start one Keycloak node configured with a remote-cache
3. Populate Keycloak  using admin console (one realm, one client, one role
and one user)
3. Ask for an access token with curl (no client_secret)

Than, in Codec21.readCacheEvent():

case CLIENT_CACHE_ENTRY_CREATED:
   Object createdKey = dataFormat.keyToObj(ByteBufUtil.readArray(buf),
status, whitelist); <-- BOOM

My config is:

<distributed-cache name="sessions" owners="1" remote-timeout="600000"
statistics-enabled="true">
<binary-memory eviction-type="COUNT" size="10000"/>
<remote-store cache="sessions" socket-timeout="600000"
remote-servers="remote-cache" passivation="false" fetch-state="false"
purge="false" preload="false" shared="true">
<property name="rawValues">true</property>
<property
name="marshaller">org.keycloak.cluster.infinispan.KeycloakHotRodMarshallerFactory</property>
</remote-store>
</distributed-cache>

The stack trace is (see below).

It is a config issue?
Thanks for your help
