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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
