Dozer

I am trying to use dozer to map a hibernate model to a DTO model. The
hibernate mappings use dynamic-component, which creates a java.util.Map
that contains name=value pairs--but many of the values are null. The
source for mapMap is incorrectly doing a .getClass() on the value while
iterating the map--assuming the value is not null. In this case, dozer
should simply insert a null value in the target map.

Stacktrace is here:
