ERROR [io.undertow.request] (default task-2) UT005023: Async is not supported for this request, as not all filters or Servlets were marked as supporting async


While upgrading JBOSS to Wildfly, we may observer below Exception:

"ERROR [io.undertow.request] (default task-2) UT005023: Exception handling request 
to /Sample/eventchannel: java.lang.IllegalStateException:
 UT010026: Async is not supported for this request, as not all filters or Servlets were
 marked as supporting async"

In order to avoid this error,

Upgrade the Servelet Jar version above 3.0

<dependency>
           <groupId>javax.servlet</groupId>
           <artifactId>javax.servlet-api</artifactId>
           <version>3.0.1</version>
           <scope>provided</scope>
       </dependency>


Enjoy Learning.
