the bug https://issues.apache.org/jira/browse/SMX4NMR-283 was resolved on 13/Oct/11.
But the current Fuse ESB release apache-servicemix-4.4.1-fuse-03-06 doesnt contain this changes. The FlowRegistryImpl class contains still the old code.
Why? Can you say me, when will be the change included in the Fuse ESB?
Next FUSE ESB 4.x release could pick up this fix.
It's about in 1 month.
