Customer is hitting a NPE in Seda as follows:

This works after a fresh deployment, but they want to be able to enable and disable this interceptor.

They have a requirement to be able to turn it ON/OFF with a config change.

When the config is updated it restarts the bundle (tried both direct and seda).

JBossFuse:karaf@root> config:edit com.redhat.common.auditweb

JBossFuse:karaf@root> config:propset auditweb.AuditWebOutInterceptorOnOffSwitch ON

JBossFuse:karaf@root> config:update

Now when the interceptor tries to send a message to the endpoint, the following null pointer exception is thrown.

This looks to have been addressed upstream and has made it into Fuse 6.2, but not 6.1. Do not see an associated CAMEL JIRA however.
