Mark White updated CAMEL-1865:
------------------------------
Attachment: MySplitter.java
Sure, attached.
Splitter makes a copy of the original (in.copy()) and adds a body and header,
then returns message in the list.
If it instead is changed to just return the original message in the list, it
doesn't throw NPE.
Thanks

> 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
