The internal structure of the stored data for map rtResourceDirectory has changed. We had to change the maps name in com.openexchange.realtime.hazelcast/conf/hazelcast/rtResourceDirectory.properties from rtResourceDirectory-1 to rtResourceDirectory-2 to avoid serialization conflicts.

We found out that eviction of map entries does not apply for hazelcasts MultiMap implementation. Therefore the property com.openexchange.hazelcast.configuration.map.maxId leSeconds was removed from com.openexchange.realtime.hazelcast/conf/hazelcast/rtIDMapping.properties.
