BeanUtils (uniquely) has the concept of a MappedPropertyDescriptor like the IndexedPropertyDescriptor, so that if you have acessor methods in your bean with a key parameter, then it assumes it is accessing an underlying Map. In that scenario it does indeed use the descriptor to determine the type. However if it has a Map property (i.e. has methods that set/return a Map) then there is no way to determine the type. By the time it reaches the line number you quote, then its in the later scenario and the type can't be determined - since the descriptor type should be a Map.
