Start in NotesServerSyncTask.java at pushLocalChanges (line 164), then trace how run (line 100) handles synchronization. Reproduce the failure with Notes Android 4.4.0 and inspect the server response associated with the RuntimeException; done means local Android changes synchronize successfully while preserving server-to-device synchronization.
