Raymond updated CAMEL-20866:
----------------------------
Attachment: main-xml.zip
> SEDA with exchangepattern InOnly gives sometimes multiple responses
> -------------------------------------------------------------------
>
> Key: CAMEL-20866
> URL: https://issues.apache.org/jira/browse/CAMEL-20866
> Project: Camel
> Issue Type: Bug
> Components: camel-seda
> Affects Versions: 4.6.0
> Reporter: Raymond
> Priority: Major
> Attachments: main-xml.zip
>
>
> I have Camel 4.6 running on Java 21
> When I use the following curl:
> ```
> curl -X POST --header "Content-Type: text/plain" --data 'x'
> http://localhost:9001/test
> ```
> To test the following route:
> ```xml
> <routes id="camel" xmlns="http://camel.apache.org/schema/spring";>
> <route id="1">
> <from uri="jetty:http://0.0.0.0:9001/test"/>
> <to uri="seda:2?exchangePattern=InOut"/>
> </route>
> <route id="2">
> <from uri="seda:2"/>
> <setBody>
> <constant>Y</constant>
> </setBody>
> </route>
> </routes>
> ```
> This works as expected and the result is Y.
> Now I changed the exchangepattern from 'InOut' to 'InOnly':
> ```xml
> <routes id="camel" xmlns="http://camel.apache.org/schema/spring";>
> <route id="1">
> <from uri="jetty:http://0.0.0.0:9001/test"/>
> <to uri="seda:2?exchangePattern=InOnly"/>
> </route>
> <route id="2">
> <from uri="seda:2"/>
> <setBody>
> <constant>Y</constant>
> </setBody>
> </route>
> </routes>
> ```
> When I call this flow with curl multiple times, I sometimes get the result:
> X
> And the other time:
> XX
> So the result is returned twice or even more times. I would expect only to
> get the output X (which for example works this way when I use ActiveMQ)
> By adding more SEDA endpoints this behavior can be easier reproduced:
> ```xml
