Cannot call getOutputStream(), getWriter() already called

      Description

      Similar to WFL-1276 I got “UT005023: Exception handling request to /hsb/web-services/: java.lang.IllegalStateException: UT010005: Cannot call getOutputStream(), getWriter() already called” when accessing CXFNonSpringServlet servlet that shows all web services deployed with ApacheCamel 2.13.0. The exception is was not present in WF 8.0. Even with the exception the servlet renders all available service correctly.

      Servlet:

       
      import com.parsek.hsb.commons.Hsb;
      import org.apache.cxf.Bus;
      import org.apache.cxf.transport.servlet.CXFNonSpringServlet;
       
      import javax.inject.Inject;
      import javax.servlet.ServletConfig;
      import javax.servlet.ServletException;
      import javax.servlet.annotation.WebServlet;
       
      // reuse camel bus
      @WebServlet(value = "/web-services/*", name = "HsbWebServices", asyncSupported = true, loadOnStartup = 1)
      public class ExposeCxf extends CXFNonSpringServlet {
       
          @Hsb
          @Inject
          private Bus bus;
       
          @Override
          public void init(ServletConfig sc) throws ServletException {
              setBus(bus);
              super.init(sc);
          }
       
      }
      

      Exception
