I have a maven based mule project that was original created with mule version 3.2.1. When I update my pom.xml to change mule.version from 3.2.1 to 3.3.0, I get the following exception when running my app.
I run the app from within Eclipse by launching `org.mule.MuleServer -config src/main/app/mule-config.xml’
This worked fine with 3.2.1. If I edit my pom.xml and change mule.version back to 3.2.1 it continues to run fine. However, I really need some bug fixes that are included in 3.3.0.
Any ideas?

Make sure all the Mule artifacts on the classpath are version 3.3.0. It seems you have a version mismatch as line 169 of SimpleRegistryBootstrap in mule-core-3.3.0.jar is commented out.
