this sounds like a very tricky problem. i don't have any solutions but one possible approach would be to factor so the dependencies were separated from the core. this would allow ant 1.6 support to be added alongside ant 1.5 support for the next release. jelly takes this approach. - robert --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
