Detect uncaught exceptions in UoWProcessor to ensure UoW is done even for those
uncaught exceptions
---------------------------------------------------------------------------------------------------
Key: CAMEL-3560
URL: https://issues.apache.org/jira/browse/CAMEL-3560
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.5.0
Reporter: Claus Ibsen
Assignee: Claus Ibsen
Fix For: 2.6.0
The Camel routing engines will handle this in 99.9% of the cases, but when you
shutdown a Spring AC then Spring may stop beans in whatever order and this can
cause those beans to fail operating during a graceful shutdown. And in worst
case exceptions is thrown in situations where they are not normally done.
To cater for that and other situations the UoWProcessor should detect this and
act accordingly.
This ensure the in flight registry will be tracked and we are not stuck with a
missing inflight message, causing Camel to wait for the 300 sec timeout to
shutdown.
For example just try hitting ctrl + c in that camel-example-management and you
can see such an example.
