The "bug" in the JDK mentioned in the URL causes Ant's touch to behave different from the UNIX touch-command. While it is probably not easy to force ant to behave "well", it shouldn't be too difficult to give the user a hint (message if setLastModified returns false) and to mention this in the docu. Thanks a lot for your helpful product, Martin
