Yes, this is caused by the fact that several jars provide the same package.
I'm not very used to modules with Java, but I think that, based on what
you pasted and the contents of the package, there are two sources of
problems:
- the jars in the directory jars/ of the source package (which we should
remove) : for instance one of the jars therein provides xml.apis;
- the line
	<fileset dir="${jfxDir}"  includes="*.jar"/>
in the patched antbuild/build.xml , where ${jfxdir} is /usr/share/java,
causes all installed jars in /usr/share/java to be searched for
modules... and libbatik-java ships a lot of subjars and one super-jar
(batik-all.jar) which gathers them all. This is the reason for the
errors involving batik on the last lines you pasted.

I can give it a try and keep you informed!
