FULL PRODUCT VERSION :
Java 1.6

ADDITIONAL OS VERSION INFORMATION :
Windows Vista Business Edition

A DESCRIPTION OF THE PROBLEM :
File.canWrite() always returns false for User folders such as Desktop, Contacts and so on.  This happens for both Admin and Limited User in widows Vista.


On a normal folder under C Drive it return true.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
File file = new File("C:\\Users\\Limited User\\Desktop");
System.out.println("Desktop can write : " +file.canWrite());

will print false

 file = new File("C:\\Users\\Limited User\\Desktop\\myfile.txt");
 System.out.println("File On  Desktop "+ file.canWrite());

will also print false

but if you continue to write the file, it will write the file myfile.txt on the desktop folder.
		
 file = new File("C:\\blah");
		System.out.println("Only folder can write : " +file.canWrite());
(folder does't exist from before) This will return true. which is correct as i want to create that folder.


		

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
should return false, to use "canWrite()" to display a application specific error message.
ACTUAL -
it always return false,

REPRODUCIBILITY :
This bug can be reproduced always.
