Steps to reproduce;

1. Create simple route with splitter pattern; e.g.

<route>
<from uri="jms:IN_QUEUE"/>
<split><method bean="MySplitter" method="doSplit"/>
<to uri="log:route.log"/>
</split>
</route>

2. Set DEBUG logging on for org.apache.camel classes, e.g.

log4j.logger.org.apache.camel=DEBUG

3. Fire message into route - message fails with NPE inside Camel
