I would expect that if you try to delete the file in Explorer or in a 
command window that you also get an "Access denied" error.

The issue is that java.io.File has many oddities, on Windows in 
particular. In this case it resets the file attributes before it deletes 
the file so this is why it does not fail as might be expected. It is 
behavior that dates back >10 years and so would be risky to change now. 
It has several other oddities like this, just one of the reason why it 
wasn't re-implemented to use the new API.
