      We need to replace the check by a check that verifies we are not writing data. If that's the case, we close the channel. If not, we just let the listener be called as many times as necessary.

      We need to replace the check by a check that verifies we are not writing data. If that's the case, we close the channel. If not, we just let the listener be called as many times as necessary.

      There is a check for a loop in the listener triggered by AbstractFramedStreamSinkChannel.resumeWritesInternal:

                              if (loopCount++ == 100) {
                            //should never happen
                            UndertowLogger.ROOT_LOGGER.listenerNotProgressing();
                            IoUtils.safeClose(AbstractFramedStreamSinkChannel.this);
                            return;
                        }

      This loop count can reach 100 if we are using EJB over HTTP, and close the connection unexpectedly.
