in the definition:
<taskdef resource="net/sf/antcontrib/antlib.xml">
<classpath>
<pathelement
location="${install.prefix}/lib/ant/ant-contrib/1.0b3/ant-contrib.jar"/>
</classpath>
</taskdef>
The File and the resource in it definitely exist.
Ant 1.8.4 is used built-in here from an Izpack installer, but this doesn't play
any role here, IMHO.
The important point is, that it fails just on the first try, but on the second
on it suceeds, although there hasn't been changed anything on the appropriate
location in between time.
Note:
At the links

http://stackoverflow.com/questions/1374438/disappearing-jar-entry-when-loading-using-spi
I found some discussion about switching off caching in such cases for
UrlConnection. Maybe this could be useful also for Ant.
