      1. deploy servlet-async.war
      2. request /servet-async/hi.jsp to establish session
      3. request /servlet-async/ to start repeated long async requests
      4. In new tab, request /servlet-async/invalidate.jsp
      5. Close out /servlet-async/ tab, note exception upon last async request completion, attempt shutdown, and note hang

In new tab, request /servlet-async/invalidate.jsp 5. Close out /servlet-async/ tab, note exception upon last async request completion, attempt shutdown, and note hang

      If AsyncContextImpl.onAsyncComplete() hits an exception, that can cause following response.responseDone() calls to be missed.

      For instance:

      1. async request a starts
      2. sync request b invalidates session
      3. async request a completes

      Upon completion, the async request does not unlock and throws following exception:
