> When combining the splitter and wireTap functionality an org.apache.camel.RuntimeCamelException
(Cannot reset stream from file) will be thrown when:
> 1. a spooled StreamCache body is created in the wireTap route
> 2. the splitter route ends before the wireTap route
> The splitter will create an Exchange.STREAM_CACHE_UNIT_OF_WORK property to hold the StreamCaches
that will be created by the children of the splitter.
> When doing a wireTap in the splitter route, the property will be copied to the wireTap
route (when using the wireTap defaults).
> StreamCaches created in the wireTap route will now be added to the property as well and
will be closed when the splitter route ends.
> A possible workaround can be to create the wireTap route without copying the original
exchange.
> However I think it is better to remove the Exchange.STREAM_CACHE_UNIT_OF_WORK property
in the org.apache.camel.processor.WireTapProcessor configureExchange method.
> I attached a maven project with a test to demonstrate the issue.
