Joda-time MissingResourceException

Question

I'm getting a

java.util.MissingResourceException: Can't find bundle for base name org.joda.time.format.messages, locale en

in the following piece of code;

    DateTime start = new DateTime();
    DateTime end = new DateTime(2017, 3, 26, 12, 0, 0, 0);
    Interval interval = new Interval(start, end);


    Period period = interval.toPeriod();

    // This line is causing the exception.
    System.out.println(PeriodFormat.getDefault().print(period));

Relevant part of the stack trace:

Caused by: java.util.MissingResourceException: Can't find bundle for base name org.joda.time.format.messages, locale en

I'm using Joda Time 2.9.2 and Intellij IDEA 15.0.1 with mainly Maven

I think it is fixed now.. Yesterday it appeared to happen after reloading the bukkit/spigot (Minecraft) server this plugin was running on. It would work fine when restarting the server, but a reload would break it. But today it just all seems to work fine. Strange, no idea what caused it.

EDIT: It appears a bukkit server just doesn't handle resource bundles when reloading well at all. One reload just breaks everything wich uses resource bundles.
