------------------------------------
I can reproduce the issue and I am working on a fix.
> StreamResequencer poisoned by bad Exchange
> ------------------------------------------
>
> Key: CAMEL-4401
> URL: https://issues.apache.org/jira/browse/CAMEL-4401
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.7.1
> Environment: JDK 1.6.0_20, Linux x86_64
> Reporter: David Tombs
> Assignee: Claus Ibsen
> Priority: Minor
>
> If a StreamResequencer's configured Expression returns null for an Exchange
> (e.g., if a header does not exist) and the resequencer's pipeline is
> currently empty, the bad Exchange will be added to the pipeline.
> ResequencerEnginer.insert() succeeds in calling sequence.add() with the bad
> Exchange, but throws an Exception when calling sequence.successor(). This
> results in the message ending up at the Error Handler but the bad Exchange
> still in the Engine's sequence. Probably insert() should be probably be more
> transactional.
> After this happens:
> 1) Trying to add a further exchange (even a "good" one) results in an
> Exception when calling sequence.add().
> 2) ResequencerEngine.deliverNext() results in an Exception so no further
> messages will be delievered.
> I will attach a unit test to reproduce when I get a chance.
