Bartosz Popiela commented on CAMEL-19670:
-----------------------------------------
Thanks [~davsclaus]! One concern I have is that it will still fail when the
stream caching is enabled.
> camel-core - Splitter fails with "Caused by: java.io.IOException: Stream
> closed"

> Key: CAMEL-19670
> URL: https://issues.apache.org/jira/browse/CAMEL-19670
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 3.21.0
> Reporter: Bartosz Popiela
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 3.21.1, 3.22.0, 4.0.0
>
>
> The recent change introduced in scope of CAMEL-18619 causes Splitter to fail
> when
> {code:java}
> org.apache.camel.model.errorhandler.DefaultErrorHandlerDefinition#setUseOriginalBody{code}
> is set to true. This is because Splitter creates a new Unit of Work and it
> consumes the stream in
> {code:java}
> org.apache.camel.impl.engine.DefaultUnitOfWork#doOnPrepare{code}
> Subsequently,
> {code:java}
> org.apache.camel.impl.engine.CamelInternalProcessor.StreamCachingAdvice#before{code}
> tries to consume this stream when the split subroute is executed and it fails
> with:
> {noformat}
