Diane,
Thanks. I updated to the current CVS version of Ant.java, rebuilt the jars,
and the problem is resolved. Is there any chance of an interim 1.3.1
version (with just bug fixes) being released? I am a little uncomfortable
having a custom, modified version of the ant jar. I'd rather have an
"official" version and a directory of extra/optional task classes.
as always, thanks!
-Mark
