Hi, How are you guys doing with the Jetty+Comet? I'm getting the exception below, consistently. This is on a physical ADP1/1.1, on WiFi.
This is using CONNECTOR_SOCKET mode. CONNECTOR_SELECT_CHANNEL mode does not work at all. Another problem is that this exception is in a thread and is not visible to the Comet code.
