ClassNotFoundException using Jetty 10 and its reactive client

[urferr]

Affects: Spring Boot 2.5.2, Spring Framework 5.3.8, Jetty 10.0.5 and Jetty Reactive Client 2.0.3

I tried to use Jetty 10 together with latest Spring Boot/Framework. Unfortunately i run into a ClassNotFoundException in the method org.springframework.http.client.reactive.JettyClientHttpRequest.writeWith because in Jetty Reactive Client 2 the class PublisherContentProvider which is instantiated there does not exist anymore. Most probably now the new class PublisherRequestContent which is quite similar should be used
