I am developing RESTEasy Example. In this example I am using all latest dependencies and deploying om tomcat 8.x version. I can successfully deploy the application but when I am launching the url: http://localhost:8080/RESTfulExample/rest/restwebservice/list, I see following errors are coming. Please guide what is going wrong here.

(For those who find the question, working with quarkus)

Using this setup routine:

mvn io.quarkus:quarkus-maven-plugin:0.16.1:create     -DprojectGroupId=com.sample     -DprojectArtifactId=hello-quarkus     -DclassName="com.sample.DemoEndpoint"     -Dpath="/persons"

To fix the issue described here, I had to add this dependency.

<dependency>
  <groupId>io.quarkus</groupId>
  <artifactId>quarkus-resteasy-jsonb</artifactId>
</dependency>

here is my full pom.xml after I added the above dependency. Again, 99% of the below pom.xml came from the mvn command above.
