--------------------------------------

             Summary: StreamCaching does not work with FTP2-components localWorkingDirectory
                 Key: CAMEL-9694
                 URL: https://issues.apache.org/jira/browse/CAMEL-9694
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.16.2
            Reporter: Jostein Gogstad


>From the [FTP2-components documentation|https://camel.apache.org/ftp2.html] we read that the {{localWorkDirectory}} attribute can be used to download the file up-front. Stream caching does not work in conjunction with this option.

It fails with:

Looks like the stream caching isn't invoked at all.
