In the Ant 1.5.1 distribution, the ant.jar has a Manifest.mf file that contains the following entry:
Class-Path: xml-apis.jar xercesImpl.jar optional.jar xalan.jar. I am working on the Ant integration for the Eclipse project and this entry is causing us some problems to do with classloading (specifically excluding optional.jar from the classpath if the user has indicated to do so). I am interested in the reason for these entries? Thanks for your time Darins
