> {{WSConverter.convertCalendar}} appears heavily in some profiling traces.
> {{WSConverter.convertCalendar}} uses {{DatatypeFactory.newInstance()}} every time but
calling this is known to be quite slow under current JVMs because it does heavy classloading

> We should use one of the recommended solutions to avoid this.
