camel-file - Some Component Parameters have a different behaviour when used with Poll Enrich

Using the following file route definition

from("file:data/inbox?fileName=File-1.txt" +
        "&charset=UTF-8" +
        "&preMove=Staging" +
        "&move=Success/${file:name.noext}-${date:now:yyyyMMddHHmmssSSS}.${file:ext}" +
        "&moveFailed=Failed/${file:name.noext}-${date:now:yyyyMMddHHmmssSSS}.${file:ext}"
)
        .log("Finished polling...");

results in the following behaviour:

• File consumed from inbox directory - OK
• File pre-moved to inbox/Staging directory for processing - OK
• File moved to 

  inbox/Success/${file:name.noext}-${date:now:yyyyMMddHHmmssSSS}.${file:ext}

  when processing finished successfully - OK

This functions as expected.

Using the exact same URI definition with the Content Enricher EIP pollEnrich using the following route

from("timer:start?delay=1000")
        .pollEnrich()
        .simple("file:data/inbox?fileName=File-1.txt" +
                "&charset=UTF-8" +
                "&preMove=Staging" +
                "&move=Success/${file:name.noext}-${date:now:yyyyMMddHHmmssSSS}.${file:ext}" +
                "&moveFailed=Failed/${file:name.noext}-${date:now:yyyyMMddHHmmssSSS}.${file:ext}"
        )
        .log("Finished polling...");

results in the following behaviour:

• File consumed from inbox directory - OK
• File pre-moved to inbox/Staging directory for processing - OK
• File moved to

   inbox/Staging/Success/-${date:now:yyyyMMddHHmmssSSS}/${file:name}

Which is NOT AS EXPECTED.

As the behaviour differs even though the exact same URI is defined for the file consumers, I'd be inclined to regard this as unintended behaviour and thus a bug. What do you guys think?

This strange behaviour also seems to have been discussed here back in 2016:
