Backport of #12230 to 3.10.x.
The configuration of the backported feature doesn't depend on XSD changes, but it is based on following Hazelcast group properties:
hazelcast.serialization.filter.enabled
false
hazelcast.serialization.filter.blacklist.classes
""
(empty)hazelcast.serialization.filter.blacklist.packages
""
(empty)hazelcast.serialization.filter.whitelist.classes
""
(empty)hazelcast.serialization.filter.whitelist.packages
""
(empty)If both
*.blacklist.classes
and*.blacklist.packages
properties are empty and deserialization protection is enabled, then a hardcoded list of well known vulnerable classes and packages is used.
