            Description

            Servlet 3.0's AsyncContext uses a timeout mechanism for pending requests. The default timeout is dependent on the container. However, this timeout can potentially interfere with ICEpush' heartbeat mechanism. When a pending request gets timed out by Servlet 3.0 before the next ping comes in the following Exception can be experienced:

            Caused by: java.lang.IllegalStateException: The request associated with the AsyncContext has already completed processing.
