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).
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:
The server responds with HTTP/1.1 101 Switching Protocols.
I excluded CXF dependencies from Apache Camel and I downgraded it to 3.5.6 version and there wasn't this problem
