JVM Xalan implementation is no longer overridden in 6.2

In JBoss 6.1.0, the lib/endorsed folder contained an implementation of Xalan. Moreover, the etc/system.properties contained 2 lines that were overriding the default implementation in the JVM.

javax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
javax.xml.transform.TransformerFactory=org.apache.xalan.processor.TransformerFactoryImpl

In JBossFuse 6.2.0, this is not the case anymore and we encounter errors on AIX:

javax.xml.transform.TransformerConfigurationException: com.ibm.xtq.xslt.jaxp.HandledRuntimeException: Can't find resource for bundle xxx.MyBundle, key Property 'http://javax.xml.XMLConstants/property/accessExternalDTD' is not recognized.

If we modify our 6.2.0 to be similar to the 6.1.0, the problem disappears.

Is it possible to modify the standard packaging of the 6.2.0 to reflect the 6.1.0?
