Description

We have a JAXWS based service and we enabled the transformation feature based on https://cxf.apache.org/docs/transformationfeature.html, but then we noticed that 'charset' is missing in response Content-Type.  This is probably due to "disable.outputstream.optimization" being set to true by TransformOutInterceptor but the documentation states that "disable.outputstream.optimization" needs to be set to true prior to CXF versions 3.2.6 and 3.1.17.

We are using 3.2.6 and we even upgraded to 3.2.12 and the behavior is the same.  I also checked TransformOutInterceptor in master branch and it is still setting "disable.outputstream.optimization" to true.

Is there a workaround for this issue in 3.2.x branch and can this be fixed in future releases?

 

Here are part of the headers with transformation:

HTTP/1.1 200 
Content-Type: text/xml
Transfer-Encoding: chunked

And here are part of the headers when transformation is not used:

HTTP/1.1 200 
Content-Type: text/xml;charset=UTF-8
Transfer-Encoding: chunked
