Once upon a time DirectoryScanner used to return files in a predictable order - something like DFS where the files from directories appear as directories are visited in DFS order. The order of files coming from the same directory as well as directories at the same height in the tree dependend on File.list and likely was in lexicographic order. This still is true if there is a basedir and DirectoryScanner decides that it needs to scan the full tree, but starting with rev 274819 (i.e. <https://issues.apache.org/bugzilla/show_bug.cgi?id=20103>, which means Ant 1.6) this is not true if there are only include patterns that don't start with wildcards. In the later case only the directories that could be included will be scanned and order of directories is undefined (they get added as keys to a map and then scanned in iterator order of the map). Given that this happened such a long time ago, we can savely assume that in general order of files/directories returned by DirectoryScanner is not defined.
