Everything works fine until I add the xml formatter. When I do so I get the
following:

I'm running ant 1.5.3-1.

Here's the jnit section of my build.xml file:

 <target name="test" depends="test-compile"
  description="JUnit tests">
  <junit haltonfailure="true" printsummary="false" >
   <classpath refid="test.classpath" />
   <formatter type="brief" usefile="false" />
   <formatter type="xml" />
   <batchtest todir="${test.data.dir}">
    <fileset dir="${test.dir}" includes="**/*Test.class" />
   </batchtest>
  </junit>
 </target>

Any help appreciated :)
