[news.eclipse.platform] Extending Folder resource

["Rahul Kamdar" <rtkamdar@xxxxxxxxxxxxxxxxx>]

Hi,

I want to extend the org.eclipse.core.internal.resources.Folder to create my 
own type of a Folder and add to the behavior and some of my own 
manipulations. When I try to directly extend it, the constructor returns a 
ClassCastException. Even if I try to cast a folder object to my own custom 
folder, I get the same ClassCastException.

We cannot extend classes defined under org.eclipse.core.internal.resources, 
is it? Would you suggest on how to try to the same! :-)

Thanks.
