David Liu updated CXF-3429:
---------------------------
Description:
Hi,
During shutdown the CXF server, we encounter the NullPointerException from
time to time.
The issue is that ServerImpl will set MessageObserver to null, and then it
shutdown desination. however, if the server is multi-thread and probably some
thread is runing, then it can result in NullPointerException because
MessageObserver is null.
Can we fix this bug by shutdown the Destination first and then set
MessageObserver to null?
Also, do we have a workaround for this issue?
{code}
public class ServerImpl implements Server {
public void stop() {
LOG.fine("Server is stopping.");
...
getDestination().setMessageObserver(null);
getDestination().shutdown();
}
{code}
