In our software, we use j2sdkee1.3.1. Because in j2ee1.3.1.jar there exists
org.w3c.dom.* and org.xml.sax.*, so when I run junit task there always report
an error: 
java.lang.LinkageError: loader constraints violated when linking

If I use j2ee1.3.1.jar to replace the ${ANT_HOME}/lib/xml-apis.jar, the ant 
cann't run.
But I must use j2ee1.3.1.jar for some other functions.
I have change the includeantruntime attibute of <junit>, but it does not work.
From the docs, I think it should work to use j2ee1.3.1.jar and ignore xml-
apis.jar.

If I delete org.w3c.dom.* from j2ee1.3.1.jar, it work. But it is apparently a 
bad method. 

How to resolve it?

Thanks!
