[jira] [Commented] (CAMEL-22021) camel-test - NPE on DefaultMessage.typeConverter in CSB with AdviceWith happens randomly

["Vincent Paturet (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-22021?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17947811#comment-17947811 ] 

Vincent Paturet commented on CAMEL-22021:
-----------------------------------------

As far as I can see, it is always the same unit tests that fail, and they all start from pubsub, and they all use advice-with.

The error is triggered from a thread belonging to the pubsub thread pool (thead name = [GAX-n]).
I cannot confirm that it affects only unit tests: we did not take the risk to roll out this version in production before clarifying the root cause of this bug.
The bug can be reproduced with Camel 4.7.0. I cannot reproduce it with Camel 4.6.0.

> When upgrading from Camel 4.4.5 to Camel 4.8.6 or 4.10.3 or 4.11.0, some unit tests fail randomly with the following error:
> {code:java}

> - The failure is random (once every 3-4 runs)
> - The unit tests use @CamelSpringBootTest and @UseAdviceWith and start the context manually: context.start()
> - The tests that fail seem to always use message aggregation (org.apache.camel.processor.aggregate.AggregateProcessor)
> The error being triggered randomly I cannot come up with a simple reproducer test case.
> I can share code and more details if needed.
