TransformerFactoryImpl was loaded incorrectly if xalan:xalan is in the classpath #49

My project depends on xalan:xalan transitively. During SchemaGen, I got the following exception:

I think it is caused by the META-INF/services/javax.xml.transform.TransformerFactory file inside xalan:xalan jar. it binds the implementation to org.apache.xalan.processor.TransformerFactoryImpl instead of com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl.

Maybe you can consider this solution http://stackoverflow.com/questions/5447633/how-to-prevent-xalan-jar-that-has-meta-inf-services-javax-xml-transform-transfor
