The main reason for the Windows failure is that for some reason the default windir was not accessible - this check will avoid the situation where we are testing the icon for non-accessible folder - because in this case we will return the default UIManager icon for a file or a folder and this icon is not multi-resolution. On Mac it leads to the IconUIResource being returned and this Icon representation can not be casted to ImageIcon hence test fails.
