--------------------------------------
Thanks for your replies! We rely on oneway and we will not be able to apply the
workaround. I hope you can troubleshoot this soon!
> Camel 3|CXF: ParsingErrors with OneWay Messages
> -----------------------------------------------
>
> Key: CXF-9091
> URL: https://issues.apache.org/jira/browse/CXF-9091
> Project: CXF
> Issue Type: Bug
> Reporter: Manuel Shenavai
> Priority: Major
>
> Hi everyone,
> we recently moved from Camel 2 to Camel 3 and we are now observing the
> following problem with CXF. If a OneWay message exceeds a certain length, the
> messages fail with a parser error like:
> Caused by: java.lang.IllegalStateException: Current event not START_ELEMENT
> or END_ELEMENT

> The error will not happen if we reduce the length of the message or if we
> change it from OneWay to ResponseReply. This indicates a problem in the async
> decoupling of the request.
> During debugging I found that the HTTP thread is used to handle the request.
> But the actual processing of the message happens in new thread. Maybe the
> input stream is closed after the http thread is finished (HTTP 202) and the
> spawned thread cannot read the full content anymore.
> I created the following reproducer based on Spring Boot:
> [https://github.com/mash-sap/cxfOneWayError/tree/main]
> CXF: 3.6.5
> Camel CXF: 3.17.0
> Tomcat: 9.0.83
