    /**
     * If any non-primitive Java Object gets serialised more than just one time,
     * then we write a JsonPointer to the first occurrence instead.
     *
     * This will effectively also avoid endless loops in data with cycles!
     *
     * An example: Assume you have a Person with a name 'Sarah' and her daughter,
     * a Person with the name 'Clemens' both stored in a JSON array.
     * Given the Java Code:
     * <pre>
     * Person sarah = new Person("Sarah");
     * Person clemens = new Person("Clemens");
     * clemens.setMother(sarah);
     * Person[] family = new Person[]{sarah, clemens};
     * </pre>
     * Transformed to JSON this will now look like the following:
     * <pre>
     * [{"name":"Sarah"},{"name":"Clemens","mother":"/0"}]
     * </pre>
     * That means instead of serialising 'mother' as full object we will
     * now only store a JsonPointer to the Person 'Sarah'.
     *
     * When deserialised back Johnzon will automatically de-reference the JsonPointer
     * back to the correct instance.
     *
     * Possible values:
     * <ul>
     *     <li>{@code true}: deduplicate objects</li>
     *     <li>{@code false}: do <b>not</b> deduplicate objects</li>
     *     <li>{@code null}: dedupliate based on the {@link JohnzonDeduplicateObjects} annotation. This is the default</li>
     * </ul>
