DateFormatUtil
> Classloading deadlock in TrieField

> When starting a test Sol instance, it locks up sometimes. We took a thread
> dump and all threads are trying to load classes via Class.forName() and are
> stuck in that method. One of these threads got one step further into the
> <clinit> of TrieField where it creates an internal static instance of
> TrieDateField (circular dependency). I don't know why this locks up exactly,
> but this code smells anyway. So I removed that instance and made the used
> methods static in TrieDateField.
> This does not completely remove the circular dependency, but at least it is
> no more in <clinit>. For the future someone may extract a util class to
> remove the circular dependency.
