Description

The error I get...

java.lang.ClassCastException: org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser

...is usually caused when an application is specifically looking for Xerces classes, instead of always going through JAXP interfaces and factories.

My application uses XSLT 2.0 features, which are not supported by Xerces/Xalan. So I have a file in my JDK lib directory named "jaxp.properties"...

# JAXP Factories
javax.xml.parsers.SAXParserFactory       = oracle.xml.jaxp.JXSAXParserFactory
javax.xml.parsers.DocumentBuilderFactory = oracle.xml.jaxp.JXDocumentBuilderFactory
javax.xml.transform.TransformerFactory   = oracle.xml.jaxp.JXSAXTransformerFactory

...which causes the JDK to default to the Oracle parser, which supports XSLT 2.0.

My hunch is that somewhere in the code the JAXP TransformerFactory is called, which returns the Oracle object, but someone is assuming that the Xerces object will be returned and are casting the object to get at some Xerces specific feature.

It's not a problem with checkstyle itself but with ant's style task that is used to transform the results. Did you load the oracle dependency in the root classloader? See http://maven.apache.org/maven-1.x/faq.html#BadXSLT

Actually, I think there is a change that should be made in the plugin.jelly file, before executing the Ant 'style' task (line 235), there should be a line line...

${systemScope.setProperty('javax.xml.transform.TransformerFactory','org.apache.xalan.processor.TransformerFactoryImpl')}

...which will change the system property to make sure JAXP returns the Xalan transformer factory to Ant, because the "style" tag requires Xalan specifically. I made the change locally and it works fine.

Also, maybe you'll need to add Xalan as a dependency for the plugin, since it uses the Ant "style" tag, which requires Xalan. Really this is an Ant problem, since it should use only standard JAXP methods. But since it requires Xalan, now so does the CheckStyle Plugin.

Yep, that worked. Although my personal preference is to use the latest version of stuff like Xalan, which is 2.7.0. I don't know if it matters much though.

I used this version for compatibility with other plugins.
We are considering upgrading xalan (see the comments at MPPDF-51), but we need to do a lot more testing.
