-------------------------------------
Summary: IOUtils.isEmpty returns false if isAvailable is zero and
no marks are supported
Key: CXF-7514
URL: https://issues.apache.org/jira/browse/CXF-7514
Project: CXF
Issue Type: Bug
Components: Core, JAX-RS
Reporter: Sergey Beryozkin
Fix For: 3.2.1
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...
