JAXP XSLT transformer using wrong implementation by default

I've got a Tomcat 5.5 web application that uses the Apache Commons-Configuration library to generate an XML configuration file at runtime. Commons-Configuration, in turn, uses the javax.xml.transform JAXP API to accomplish this.

Since upgrading to Java 7, the operation fails with the following error message:

Caused by: javax.xml.transform.TransformerFactoryConfigurationError: Provider org.apache.xalan.processor.TransformerFactoryImpl not found
    at javax.xml.transform.TransformerFactory.newInstance(Unknown Source)

In past releases, I've never bundled xalan.jar, instead relying on the platform default XSLT implementation.

Some things I've checked:

Running with -Djaxp.debug=1 produces the following output:

JAXP: find factoryId =javax.xml.transform.TransformerFactory
JAXP: loaded from fallback value: org.apache.xalan.processor.TransformerFactoryImpl

Where's this fallback value coming from? Oracle ships the Xalan transformer, but since 1.7 has repackaged it as com.sun.org.apache.xalan.processor.... Shouldn't that be the fallback value?

The same issue i was also getting with Glassfish server V3.1 and by placing xalan-2.7.0.jar in $GLASSFISH_HOME\lib\endorsed directory the issue is resolved.

Found the issue myself. It turns out that I had the apache-tomcat-5.5.23-compat files installed, as I was migrating from Java 1.4.2. The solution was to remove everything under the $CATALINA_HOME/common/endorsed directory (in particular xercesImpl.jar and xml-apis.jar) and the bin/jmx.jar files.
