        public static Factory getInstance​(java.lang.Object prototype)
        Factory method that performs validation.

        Creates a Factory that will return a clone of the same prototype object each time the factory is used. The prototype will be cloned using one of these techniques (in order):

        • public clone method
        • public copy constructor
        • serialization clone

            WARNING: from v3.2.2 onwards this method will return a Factory that will throw an UnsupportedOperationException when trying to serialize or de-serialize it to prevent potential remote code execution exploits.

            In order to re-enable serialization support the following system property can be used (via -Dproperty=true):

        prototype - the object to clone each time in the factory
        the prototype factory
        java.lang.IllegalArgumentException - if the prototype is null
        java.lang.IllegalArgumentException - if the prototype cannot be cloned
