Hi We are affected by same issue. Seams like regression from Camel 2.8.x, in witch routes with combination of DLQ EH and onException clauses (for fast redelivery) worked fine (we have many such routes in production). As now we can't upgrade to Camel 2.10 because of this issue. I've try to debug routes - no luck. Only strange thing that I figured out is:
In RedeliveryErrorHandler when onException redeliveries is exhausted the RedeliveryData used by handleException() given from onException configuration instead of DeadLetterChannel. As result RedeliveryData.handledPredicate is invalid. Claus, point me please where to see to figure out cause of issue?
