Hi

Yeah would assume depends-on attributes ought to tell blueprint in
which order to shutdown its beans etc.
Or somehow you can try to get <camelContext> as being the first "bean"
blueprint should try to shutdown, as then Camel will complete all its
inflight messages first, and hence the <beans> should be shutdown
later.

You can also enable cache on the bean endpoint to avoid the lookups

  <bean uri="ref:myBean?cache=true" />

And see if that helps.
http://camel.apache.org/bean


And when you see this error, does that only happen if the aggregator
has messages that hasn't been fully aggregated, but are forced to be
completed when stopping? eg this doesn't happen when stopping and the
aggregator is empty?
