Environment:
==========
BE 5.x

Symptoms:
=========
A scorecard is used in the agent and there is backingstore.

Cause:
=====
A key value needs to be added to the CDD file for the inference engine to start up correctly.

Resolution:
=========
In the CDD file add a value for the key under the inference-class.   For example:

&ltref&gtinference-class</ref>
&ltkey&gtAgent1</key>

This only needs to be added for the inference-agent.

TIBCO BusinessEvents (BE) Inference engine dies with a run time error of java.lang.NullPointerException.
