Clojurians Log v2

Has anyone ever had any conflicts between org.eclipse.jetty.websocket and figwheel-main? So I had my front end working just fine, but I've done some work on the back end and so my deps.edn file looks like this:

{ :deps { org.clojure/clojure       {:mvn/version "1.9.0"}
          org.clojure/clojurescript {:mvn/version "1.10.339"}
          ring/ring-core            {:mvn/version "1.7.1"}
          ring/ring-jetty-adapter   {:mvn/version "1.7.1"}
          compojure                 {:mvn/version "1.6.1"}
          reagent                   {:mvn/version "0.8.1"}
          re-frame                  {:mvn/version "0.10.8"}}
  :paths ["src" "resources"]
  :aliases { :depstar
              { :extra-deps
                {seancorfield/depstar {:mvn/version "0.2.4"}}}
            :fig 
              { :extra-deps
                { com.bhauman/figwheel-main       {:mvn/version "0.1.9"}
                  com.bhauman/rebel-readline-cljs {:mvn/version "0.1.4"}}
                :extra-paths ["target" "test" "resources"]}
            :build {
              :main-opts ["-m" "figwheel.main" "-b" "dev" "-r"]}}}

I get compilation errors unless I comment out the ring/ring-jetty-adapter dependency.

Exception in thread "main" java.util.ServiceConfigurationError: org.eclipse.jetty.websocket.api.extensions.Extension: Provider org.eclipse.jetty.websocket.common.extensions.fragment.FragmentExtension could not be instantiated
	at java.base/java.util.ServiceLoader.fail(ServiceLoader.java:581)
	at java.base/java.util.ServiceLoader.access$100(ServiceLoader.java:390)
	at java.base/java.util.ServiceLoader$ProviderImpl.newInstance(ServiceLoader.java:803)

any ideas?
