PaxWeb: Undertow and async filter/servlet

[Jérémie Brébec]

Hi,

I have an application using Karaf 4.1.1, PaxWeb and the jetty provider.

For testing purpose, I am trying the new undertow provider of pax web 6 : Most of my application seems to work, exception for my notification servlet, using the Servlet3 "startAsync" API. Undertow fails with this exception :

Caused by: java.lang.IllegalStateException: UT010026: Async is not supported for this request, as not all filters or Servlets were marked as supporting async

at io.undertow.servlet.spec.HttpServletRequestImpl.startAsync(HttpServletRequestImpl.java:948) ~[?:?]

at javax.servlet.ServletRequestWrapper.startAsync(ServletRequestWrapper.java:432) ~[104:javax.servlet-api:3.1.0]

at javax.servlet.ServletRequestWrapper.startAsync(ServletRequestWrapper.java:432) ~[104:javax.servlet-api:3.1.0]

at xxxx.security.authentication.web.CookieBasedSecurityContextRepository$Servlet3RequestWrapper.startAsync(CookieBasedSecurityContextRepository.java:168) ~[81:xxx.security-core:1.11.0.SNAPSHOT]

at javax.servlet.ServletRequestWrapper.startAsync(ServletRequestWrapper.java:432) ~[104:javax.servlet-api:3.1.0]

at org.springframework.security.web.servletapi.HttpServlet3RequestFactory$Servlet3SecurityContextHolderAwareRequestWrapper.startAsync(HttpServlet3RequestFactory.java:167) ~[?:?]

This application is securised with a SpringSecurity Filter, which has been register as an osgi service, with the property "osgi.http.whiteboard.filter.asyncSupported" = "true", (and works fine with Jetty).

Is there a configuration to add to use an async servlet with undertow ?

Not sure about it, but after reading the code, it looks like the Undertow provider doesn't respect the FilterModel.isAsync(), and don't call the undertow FilterInfo.setAsyncSupported(..) [1]

Hi, 

sounds like you found a bug. Care for opening a jira issue for that? 
In case you don't have a Jira account yet, let me know so I can enable that for you :)
