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 but the process just fails. I attached a scenario to reproduce the problem to this mail (ExceptionHandling.java).
Is this the expected behavior? If yes, is there a way to make sure that the
exception-handling is executed anyways?
Thanks in advance &
Best regards,
Manuel
