Hi I get a Jetty conflict between 

com.cognitect.aws/api 0.8.612
and 
io.pedestal/pedestal.jetty 0.5.10
They load different versions of Jetty which appear to play badly together 
org.eclipse.jetty/jetty-http 9.4.48.v20220622
tries to call in to 
org.eclipse.jetty/jetty-servlet 9.4.44.v20210927
and ends up with an UnsupportedOperationException. is this a known problem? and is there a standard fix? Stack trace looks like 
java.lang.UnsupportedOperationException: Use .getMatched(String) instead

should I force io.pedestal/pedestal.jetty to use the new Jetty libraries?

souenzzo18:12:40

TLDR: yes. I think that you should simply use the newer ones.

We have an alpha release of Pedestal 0.5.11 that's actually reasonably stable and updates the Jetty dependencies to 9.4.48.v20220622. I'm not at the office now so I'm having trouble tracking down where the dependency from aws/api to jetty comes from.

hlship20:12:44

I may have a few minutes tomorrow to track this down. I'd check the dependency tree of aws/api.

just to confirm - I can make my problem go away with this deps.edn configuration 

io.pedestal/pedestal.jetty {:mvn/version "0.5.10"
                                    :exclusions [org.eclipse.jetty/jetty-alpn-server
                                                 org.eclipse.jetty/jetty-security
                                                 org.eclipse.jetty/jetty-server
                                                 org.eclipse.jetty/jetty-servlet
                                                 org.eclipse.jetty/jetty-util-ajax]}
        org.eclipse.jetty/jetty-alpn-server {:mvn/version "9.4.48.v20220622"}
        org.eclipse.jetty/jetty-server {:mvn/version "9.4.48.v20220622"}
        org.eclipse.jetty/jetty-servlet {:mvn/version "9.4.48.v20220622"}

com.cognitect/http-client has a dep on jetty-client 9.4.48.v20220622 pedestal-jetty 0.5.11-alpha-1 also has a dep on 9.4.48.v20220622, so using the alpha will also fix this issue.
