[cp-patches] FYI: Return empty list for unreadable directories

[Mark Wielaard]

Hi,

When a directory isn't readable we would return null, but applications
expect an empty list of files. This is according to the docs which say
that null is only returned if the File isn't an directory. And we do
check that first.

    * java/io/File.java (list): Return empty list for unreadable dirs.

Committed,

Mark
