      1. Create Wildfly 22 runtime and use Java 11 as its execution runtime
      2. Create Dynamic Web Project and associate it with wf22 runtime, Next
      3. Toggl to generate web.xml file
      4. Finish creating project
      5. Delete project and its all content (delete from disc option)
      6. Assert: Project is deleted and no error appeared
      Actually, project seems to be deleted but error are present. Moreover, in itests I got more and more errors while recreating project and adding JAX-RS/WS features. I am not really sure if that is just an outcome of former exceptions...

    Description

      I got similar NPE while running websocket itests, during creating and setting up project for testing purpose. It happens while I am editing java class file with JAX-WS/RS annotations.
