The test example below works in 2.15.4, but fails in 2.16.0.
In 2.15.4, an exception thrown from an AggregationStrategy bubbles up into
the doTry/doCatch, and is successfully caught.
In 2.16.0, the exception is ignored, and "WARN
org.apache.camel.util.EventHelper - Error notifying event ..." is seen.
A fault in 2.16.0? Or what do I need to change, or how can I rewrite this
pattern to be compliant with 2.16.0?
Many thanks :-)
