i am currently doing a POC to add graphql to a mono reactive spring boot project with uses jetty. existing reactive spring boot configuration is

implementation "org.springframework.boot:spring-boot-starter-webflux"
implementation ("org.springframework.boot:spring-boot-starter-web") {
     exclude module: "spring-boot-starter-tomcat"
}
implementation "org.springframework.boot:spring-boot-starter-jetty"
implementation "org.springframework.boot:spring-boot-starter-reactor-netty:2.4.4"
implementation "io.projectreactor:reactor-core:3.4.6"

springBootVersion = '2.1.16.RELEASE

which is working perfect.. when i add below graphql configuration

implementation "com.graphql-java:graphql-spring-boot-starter:5.0.2"
implementation "com.graphql-java:graphql-java-tools:5.2.4"
implementation "com.graphql-java:graphiql-spring-boot-starter:5.0.2"

and schema having simple subscription which returns mono and corresponding resolvers. when i treid to start the application loading all schemas and resolvers but at the end giving below exception

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'serverEndpointExporter' defined in class path resource [com/oembedler/moon/graphql/boot/GraphQLWebAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available
