I am using WildFly Server 9.0.0 Final, Javax ws, Jersey for developing Rest APIs. For all the responses whose httpStatus code is 204, the wildfly server adds Transfer encoding Chunked in the response header, which is not correct as per the Rest Standards. Because of this behavior some of the RestAPI clients hang, as they keep waiting for the response (which is not at all there).

To verify the issue, I tried the same with Springboot instead of deploying the war in WildFly and the Response Header was not added with Transfer Encoding Chuncked.

Let me know if some other information is required to fix this issue, if this is already fixed is there any patch for this issue.
