Perhaps slightly better is this variant, which adds doc for the @serialField's.

/**
 * @serialField rnd long
 *              seed for random computations
 * @serialField initialized boolean
 *              always true
 */
private static final ObjectStreamField[] serialPersistentFields = {
        new ObjectStreamField("rnd", long.class),
        new ObjectStreamField("initialized", boolean.class),
};

/**
 * Saves the {@code ThreadLocalRandom} to a stream (that is, serializes

it). */ private void writeObject(java.io.ObjectOutputStream out) throws java.io.IOException {

    java.io.ObjectOutputStream.PutField fields = out.putFields();
    fields.put("rnd", UNSAFE.getLong(Thread.currentThread(), SEED));
    fields.put("initialized", true);
    out.writeFields();
}
