[jira] Closed: (GERONIMO-2766) cannot restart a tomcat http
connector from the console

Paul McMahan closed GERONIMO-2766.
----------------------------------
Resolution: Won't Fix
The NullPointerException occurs when a connector has been stopped but its socket has not closed yet. While the socket is still open any request it receives will be processed by the orphaned connector which has been stopped and removed from its container, resulting in the NPE. The socket usually closes immediately but sometimes it lingers for a few seconds.
Geronimo could avoid this NPE by not removing a connector from its container when the connector is stopped. But that would require adding the connector to the container in the connector's constructor, making it impossible to create a connector without automatically adding it to the container. It is safer to add the connector to the container when the connector is explicitly started, and remove the connector from the container when the connector is stopped. This is the current behavior in geronimo, which after making this investigation I think should remain intact despite the possibility of allowing a harmless NPE during the small time widow before the socket closes.
