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.
