problems with the invalid header “Transfer-Encoding: chuncked” with status code 101.
When a websocket connection is opened (using javax.websocket.*), we are facing problems with the invalid header “Transfer-Encoding: chuncked” with status code 101.
According to RFC this header must NOT be set in any status code 1xx.
https://tools.ietf.org/html/rfc7230#section-3.3.1
A server MUST NOT send a Transfer-Encoding header field in any
response with a status code of 1xx (Informational) or 204 (No
Content). A server MUST NOT send a Transfer-Encoding header field in
any 2xx (Successful) response to a CONNECT request (Section 4.3.6 of
[RFC7231]).
