I thought of this, and rejected it. It will cause more memory churn
than is really nescessary. All the dummy empty objects. The same
goes for Static['Collections'].EMPTY_MAP, as that has too much runtime
method invocation overhead.
Altho, maybe if ofbiz auto-inserted EMPTY_MAP and EMPTY_LIST, but even
that would require a context variable lookup, for what really should
be a *real* constant value.
And, I do not want to *have* to modify *every* *single* *ftl* line
again that calls the new findByAnd.
