    Hello,<br>
    <br>
    I have JAX-RS service secured by Keycloak. It works fine on Wildfly
    8-10 and Glassfish 4. But on Tomee 7.0.1 async methods throws
    NullPointerException (sync works fine). I have created simple
    project for test on tomee 7.0.1 combination sync/async + keycloak
    and here is results:<br>
    <ol>
      <li>no keycloak + sync = ok</li>
      <li>no keycloak + async = ok</li>
      <li>keycloak + sync = ok</li>
      <li>keycloak + async = error</li>
    </ol>
    Method signature sample: <br>
    
    <br>
    @GET<br>
    public void findAll(@Suspended AsyncResponse response) <br>
    <br>
    Exception stacktrace:<br>
    <p>java.lang.NullPointerException<br>

    How this issue can be resolved? May be this is tomcat adapter bug?<br>
