Following up for posterity...
The workaround I'm going with is to create a per bundle CamelContext using
Blueprint. Each module adds routes to its own context and the onException

Hi,
I'm currently migrating an OSGI application from Camel 2.25 to 3.21. I've

Then you should not really use onException

Hi everyone,
we are using the Camel-onException error handling and found that the
exception-handling is sometimes not executed in case of error. When
StreamCaching is enabled in the route and an error happens during
TypeConversion (see stacktrace below), the exception handling is not executed
