NullPointerException while generating mapper for Map type

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Create two classes that have java.util.Map property - to make it simple 
create the same names of this specific property to tell Orika that it should 
map it 1-1. (any Map generic type, for example <String, String> is ok)
2.Create filter which extends CustomFilter that will apply in that case (to 
make sure it applies on that mapping I created TestFilter extends 
CustomFilter<Object, Object>)
3.Register filter by MapperFactory
4.Execute mapperFactory.getMapperFacade().map(source, destination.getClass()); 
on defined types with maps

What is the expected output? What do you see instead?
Expected: generated mapper and working mapping because it is straightforward

Instead: while generating mapper code it is creating filter list which apply to 
this particular mapping. When invoking appliesTo method on filter for a Map 
property it is ok, but then it is invoking appliestTo method on Map KEY ant it 
throws NullPointerExceptione - because destination paramether in appliesTo 
method is NULL.
I have attached stack trace
