Description

The recent change introduced in scope of CAMEL-18619 causes Splitter to fail when 

org.apache.camel.model.errorhandler.DefaultErrorHandlerDefinition#setUseOriginalBody

 is set to true. This is because Splitter creates a new Unit of Work and it consumes the stream in 

org.apache.camel.impl.engine.DefaultUnitOfWork#doOnPrepare

Subsequently,

org.apache.camel.impl.engine.CamelInternalProcessor.StreamCachingAdvice#before

tries to consume this stream when the split subroute is executed and it fails with:

org.apache.camel.StreamCacheException: Error during type conversion from type: org.apache.camel.dataformat.zipfile.ZipInputStreamWrapper to the required type: org.apache.camel.StreamCache with value org.apache.camel.dataformat.zipfile.ZipInputStreamWrapper@20ac325b due to org.apache.camel.TypeConversionException: Error during type conversion from type: org.apache.camel.dataformat.zipfile.ZipInputStreamWrapper to the required type: org.apache.camel.StreamCache with value org.apache.camel.dataformat.zipfile.ZipInputStreamWrapper@20ac325b due to java.io.IOException: Stream closed

Please find the unit test attached. It works with Camel 3.20.4 and fails with Camel 3.21.0.
