Comment 8 for bug 238487

Why is it that it's not necessary to put e.g. the JUnit jar in -lib, but it is necessary to put commons-net? They are both optional dependencies.

The <dtd> task loads all of ant's tasks and the only one which fails is <ftp>, which needs commons-net in the classpath.

Seems like a packaging problem to me. Perhaps there needs to be a symlink in /usr/share/ant/lib.
