>          Issue Type: Bug

>
> https://issues.apache.org/jira/browse/CXF-6891
> was about supporting the non-empty streams which return isAvailable=0 and 
> support no marks.
> The problem is, if the stream is really empty in such cases (ex DELETE) then 
> the JAX-RS filter code, 'hasEntity' has no way to return 'false' unless 
> Content-Length=0 is also set (which is not available with DELETE).
> I suspect that for 3.2.1, we actually need to return IOUtils.isEmpty() = true 
> if the stream isAvailable == 0 and stream.markSupported == false. And add a 
> property to assume the stream is non-empty under these conditions to support 
> a CXF-6891 case...
