[BUG] NullPointerException while Deleting a directory.
I apologize if this has been already reported. But could
not find anything on this when searched the bug report
database.
Tried to submit this bug through BugRat, but when I tried
to view this report online, the text for 'How to reproduce'
was missing. So mailing this to ant-dev.
With regards,
Nikhil

How To Reproduce:
-----------------
Stumbled upon this when did a build by root user and then
clean by a non-root user.
Lets take the ${build.classes} directory as the guinea pig.
1. Create the ${build.classes} directory by hand
say mkdir lib/classes (if not already exits).
2. Change it's access permissions to 000
say chmod 000 lib/classes/
(Or change the owner of the directory say to root)
3. Now run ant clean (assuming the clean target has a task
to delete ${build.classes}
And this results in a NullPointerException.
