That does not work for me, no matter what version of Xalan I put in ANT_HOME/lib, I always get:

 
Using loader null on class org.apache.tools.ant.taskdefs.optional.junit.XMLJUnitResultFormatter: java.lang.NoClassDefFoundError: org/w3c/dom/Node

	at org.apache.tools.ant.taskdefs.optional.junit.JUnitTestRunner.main(JUnitTestRunner.java:766)

Then I read:

http://ant.apache.org/faq.html#junit-no-runtime-xml

This states that the only way to fix this is to fix one's build.xml file like so:
"the easiest solution is to add

<pathelement path="${ant.home}/lib/xml-apis.jar:${ant.home}/lib/xercesImpl.jar"/>

to your task's <classpath>."
I implemented this and the build succeeded. So I am submitting the attached patch to build.xml. This path element is ignored by Java versions >= 1.4 since one must use the override mechanism to use different XML libs than what is in the runtime.

Thank you,
Gary
