question: public Serializer disableWhitelist ( ) { whitelistRequired . set ( false ) ; return this ; }
target:  Disables whitelisting for serializable types. <p> When whitelisting is disabled, types that are not registered may be serialized and deserialized by this serializer. This can pose a security risk in an untrusted network. It's recommended that users enable whitelisting and register serializable classes.
