Xilai Dai commented on CAMEL-19512:
-----------------------------------
Updated the test-setheader project and re-attached it.
The issue is not on simple language but on setHeader().
[~davsclaus], [~essobedo], Could you please re-check it with the steps in
README.txt?
> SetHeader not working anymore with InputStreamCache type
> --------------------------------------------------------
>
> Key: CAMEL-19512
> URL: https://issues.apache.org/jira/browse/CAMEL-19512
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 3.20.3
> Environment: JDK 11
> Reporter: Xilai Dai
> Priority: Minor
> Attachments: test-setheader.zip

>
> It seems there is a regression from Camel 3.20.3 which is the SetHeader not
> working anymore with InputStreamCache type.
> Given that a simple route:
> {code}
> from("timer:cTimer_1" + "?period=" + 1 + "&repeatCount=" + 1 +
> "&delay=" + 1)
> .setHeader("myheader1").constant("Hi")
> .log(org.apache.camel.LoggingLevel.WARN, "MyRoute.cLog_1",
> "header myheader1 value is: ${header.myheader1}")
> .setHeader("myheader2").constant(iscache1)
> .log(org.apache.camel.LoggingLevel.WARN, "MyRoute.cLog_2",
> "header myheader2 value is: ${header.myheader2}")
> .setBody().constant(iscache2)
> .log(org.apache.camel.LoggingLevel.WARN, "MyRoute.cLog_3",
> "body value is: ${body}");
> {code}
> the value of header.myheader2 is always null from Camel 3.20.3, whereas in
> Camel 3.20.2 or earlier version, it worked as expected.
> Attached a sample project for easily reproduce the issue.
