      public static <T> List<T> filterNulls(List<T> src)
      Remove nulls from a list. Added as a temporary kludge for some obscure Hibernate crap that adds phantom null's to Lists under some conditions. Do not collapse empty lists to null, some object constructors set the list before they begin populating it. This obviously still has the potental for nulls, but at least Hibernate doesn't appear to follow that pattern.
