Boon supports for coercion and JSON serialization gets timezone, locale, UUID, URL, URI, File and Path (it had Class but I did not advertise it)

    public static class Sample
            implements Serializable {

        private static final long serialVersionUID = 1L;

        private  URL url;
        private  URI uri;
        private  File file;
        private  Date date;
        private final UUID persistId;
        private Path path;
        private Locale locale;
        private TimeZone timeZone;

        private static final AtomicLongFieldUpdater<Sample> EFFECTIVEDATE_UPDATER
                = AtomicLongFieldUpdater.newUpdater(Sample.class, "effectiveDate");


        public Sample() {
            this.persistId = UUID.randomUUID();
            this.effectiveDate = System.currentTimeMillis();

            try {
                url = new URL("http://www.google.com");
            } catch (MalformedURLException e) {
                e.printStackTrace();
            }

            try {
                uri = new URI("http://www.google.com");
            } catch (URISyntaxException e) {
                e.printStackTrace();
            }

            file =new File("/usr/local/bin/vertx");

            date = new Date();
            path = file.toPath();
            locale = Locale.CANADA;
            timeZone = TimeZone.getTimeZone("PST");
        }


        public UUID getPersistId() {
            return persistId;
        }

        private volatile long effectiveDate;

        public final long getEffectiveDate() {
            return effectiveDate;
        }

        public final void setEffectiveDate(long effectiveDate) {
            EFFECTIVEDATE_UPDATER.compareAndSet(this, this.effectiveDate, effectiveDate);
        }
