How does one handle a java method which returns a non-public sub-type via reflection?

[jeffrey kutcher]

 Then in this case, shouldn't getChildren() not be permitted? You're exposing a non-public sub-type.

 There are many good reasons for using non-public classes in the 
implementation of a class library, the main one being to keep 
implementation details from leaking into the public API. So while I 
"get" that it causes difficulties in your specific case, I don't agree 
that the solution is to avoid using non-public syb-types.

There has to be a good reason otherwise it should be changed or eliminated [get rid of inner classes]).
