Description

When running the cactus:test-war goal with maven 1.1-beta-1 I get the following stack trace:

This seems to be caused by a change to the class org.apache.tools.ant.types.AbstractFileSet in ant 1.6.x. This class now has a new toString() method which throws the following exception

Caused by: No directory specified for FileSet.

A potential patch to CactusScannerTag.java is attached
