Hi,I am trying to get a stateful drools session to work, based on the current
servicemix 5.1.0 camel-drools example. Building and deploying the bundles /
features work fine. If I change the spring or blueprint to try to create a
stateful instance, I get a NPE exception thrown when I attempt to deploy the
bundle. Is this broken, or am I missing some other configuration?spring.xml
snippet - changed type="stateless" to type="stateful"
