--------------------------------------------------------------
I can see that this exception is thrown as you see it in the
stax2-api-3.1.4.jar source code.
It must be that the code path your app follows is different than what we see in
our Log4j unit tests.
If this is not a classpath issue, there is something in the data you are
logging that must be messing up the Log4j XML layout.
What is the message being logged that causes this stack trace?
Resolving class path issues:
Do you configure your project with Maven or are you creating a classpath for
you app manually? In an IDE?
What is your full class path? You can print your class path on the console by
looking up the {{java.class.path}} system property.
I can't run your example ATM. Hopefully someone else will.
