…zelcast instances (#22943) Apply a default JavaSerializationFilterConfig on the SerializationConfig of the Config built by Camel when no user-supplied Config or HazelcastInstance is provided. The default whitelists class name prefixes java., javax., org.apache.camel. and blacklists java.net. Affects: - HazelcastDefaultComponent#getOrCreateHzInstance (only when neither hazelcastInstance, hazelcastConfigUri, nor a referenced Config is supplied) - HazelcastUtil#newInstance() (no-arg) - HazelcastAggregationRepository#doStart (when no hazelcastInstance is supplied) - HazelcastIdempotentRepository#doStart (when no hazelcastInstance is supplied) A user-supplied JavaSerializationFilterConfig is respected and is not overwritten. Adds a HazelcastSerializationFilterHelper utility, a unit test, and an upgrade guide note for 4.21.
