The fix for https://issues.apache.org/jira/browse/IO-859 introduced this regression bug https://issues.apache.org/jira/browse/IO-874, which is triggered when a broken/dangling symlink is tried to be deleted.
Before 2.16.1, FileUtils.forceDelete() deleted broken/dangling symbolic links successfully, since then it throws FileNotFoundException. With this fix a FileNotFoundException is only thrown, when the target file does not exist AND is not a symlink. 2 tests have been added to check that a broken link is deleted and that an ok link only deletes the link but not the file itself (increase test coverage).
Note: This is my first contribution. I just signed the ICLA as JoergBudi@gmx.de, shared it with secretary@apache.org and got a receipt, but haven't got an apacheid yet (my preferred apacheid would be jbudi , but I am in no hurry in case that is handed out only after more contribs).
