Summary: HttpServletRequest.isAsyncStarted() returns false when

Servlet 3.0 isAsyncStarted testcase
In the attached example, an async request is created, but within a Runnable
started using AsyncContext.start() the isAsyncStarted() returns false.
This conflicts with the servlet 3.0 specification. Quoting chapter "2.3.3.3
Asynchronous processing" : "
public boolean isAsyncStarted() - Returns true if async processing
has started on this request, and false otherwise. If this request has been
dispatched using one of the AsyncContext.dispatch methods since it was
put in asynchronous mode, or a call to AsynContext.complete is made, this
method returns false.
"
This output is generated by Tomcat 7.0.0:
Start async()
Dispatching start()
request.isAsyncStarted()1true
Returning from doGet()
request.isAsyncStarted()2false
Before sleep()
After sleep()
request.isAsyncStarted()3false
Returning from run()
request.isAsyncStarted()4false
The following output is what we would expect and what Jetty v8.0 generates:
Start async()
Dispatching start()
request.isAsyncStarted()1true
Returning from doGet()
request.isAsyncStarted()2true
Before sleep()
After sleep()
request.isAsyncStarted()3true
Returning from run()
request.isAsyncStarted()4false
