Description

Hi 

I am using Apache Camel CXF component to integrate soap services.

Recently, I updated Apache Camel Version (3.20.x -> 3.21.0) and so Apache CXF version is changed  (3.5.6 -> 3.6.1).

CXF 3.6.1

When I invoke SOAP service, by tcpdump I can see that CXF sets http headers 'Connection: Upgrade, HTTP2-Settings', 'HTTP2-Settings: AAEAAEAAAAIAAAABAAMAAABkAAQBAAAAAAUAAEAA' and 'Upgrade: h2c' but the connection is HTTP/1.1:

.o.91v..POST /my-soap-service HTTP/1.1
Connection: Upgrade, HTTP2-Settings
Host: myhost:8080
HTTP2-Settings: AAEAAEAAAAIAAAABAAMAAABkAAQBAAAAAAUAAEAA
Transfer-encoding: chunked
Upgrade: h2c
Accept: */*
Authorization: Basic ******
Content-Type: text/xml; charset=UTF-8
SOAPAction: ""
User-Agent: Apache-CXF/3.6.1

 

 

The server responds with HTTP/1.1 101 Switching Protocols.

CXF 3.5.6

I excluded CXF dependencies from Apache Camel and I downgraded it to 3.5.6 version and there wasn't this problem

.\....X
POST /my-soap-service HTTP/1.1
Content-Type: text/xml; charset=UTF-8
Accept: */*
Authorization: Basic ******
SOAPAction: ""
User-Agent: Apache-CXF/3.5.6
Cache-Control: no-cache
Pragma: no-cache
Host: my-host:8080
Connection: keep-alive
Transfer-Encoding: chunked
