> We initialize the ReplicationSource in a background thread to avoid blocking 
> the peer modification. And when enqueueLog is called and we want to start a 
> new shipper, we will check whether the replicationEndpoint is initialized, if 
> so, we will start a new shipper. But in the initialize thread, we will 
> initialize walEntryFilter after replicationEndpoint , so it is possible that 
> when we start a new shipper, the walEntryFilter is still null and cause NPE.
