Serialization of an AddressableNode requires an additional 7 or 19 bytes (depending on whether the corresponding bind address is IPv4 or IPv6) as well as the logical name as a UTF-8 string; all on top of the 16 bytes required to serialize the JGroups/Infinispan address.

In most cases, this is completely unnecessary, as the Node can always be recreated from the address via a NodeFactory<Address>.

Known offenders are:

• org.wildfly.clustering.server.registry.CacheRegistry which stores the Node as a cache key.
• org.wildfly.clustering.server.provider.CacheServiceProviderRegistry which stores a Set<Node> as a cache value.
