Environment:
===============
TIBCO Business Events 5.x

Symptoms:
==========
Engine fails to startup.

Cause:
========
The error occurs if you have more than one collection in your CDD (Cluster Deployment Descriptor) with the same name. For example, if you have a collection under  “Rules” called “test” and you have another collection under “Destinations” called “test” on engine start-up you will see the class cast exception indicated above.

Resolution:
===========
Make sure you use different collection names in your CDD (Cluster Deployment Descriptor) under “Collections” tab.
