Deletion of orphaned Softlinks does not work
--------------------------------------------

                 Key: IO-147
                 URL: https://issues.apache.org/jira/browse/IO-147
             Project: Commons IO
          Issue Type: Bug
    Affects Versions: 1.3.2
         Environment: Debian Linux JDK 1.5
            Reporter: Stefan Lischke
            Priority: Critical


If there is an orphaned softlink a -> b, but b does not exists anymore than the 
softlink will not be removed. This happens when you call 
FileUtils.deleteDirectory() and when the linked target b is deleted earlier 
than the link.

This is caused by the "ugly" file.exists() call in forceDelete()

if (!file.exists()) {
         throw new FileNotFoundException("File does not exist: " + file);
}

if this check is not done, everything works as expected. I think this test is 
not neccessery, cause file.delete will test this better.

Please discuss and change this.

thanx

Stefan
