I see ArrayIndexOutOfBounds Exception thrown but there are three different methods in the following lines in the code.How would I read the log to find out which of the following lines the error being thrown at. Please advise.
ServerImpl.java:1870 or ServerImpl.java:1750 or TrackLocation.java:52

Code:

TrackLocation.java:52 - 
int successFlg = Server.instance.updateLocationInServer(lat, lot, 
System.currentTimeMillis(), true);

ServerImpl.java:1750 - 
addOfflineCommand("locationService", lat, lot, System.currentTimeMillis());

ServerImpl.java:1870 - 
Storage.getInstance().writeObject(appName + user + "- 
offlineCommandsLocEnc", l_noAppt);

Initializing the Storage:
public void init(Object context) 
Preferences.setPreferencesLocation("EncryptedPreferences"); 
Storage.getInstance().deleteStorageFile(Cookie.STORAGE_NAME); 
 

public class TrackLocation implements LocationListener 

private static TrackLocation instance = new TrackLocation();
private Location lastLocation;
private Timer time;

public static TrackLocation getInstance() 
 return instance;


public void stopTracking() 
 if (time != null) 
 time.cancel();
 
 time = null;
 LocationManager.getLocationManager().setLocationListener(null);


public void startTracking() 
 if (time != null) 
 stopTracking();
 
 if (Preferences.get("LocationTracking", true)) 
 long delay = Server.instance.getLoctionPollingIntervalMillis();
 LocationManager.getLocationManager().setLocationListener(this,
 new LocationRequest(LocationRequest.PRIORITY_HIGH_ACCUARCY, delay));
 time = new Timer();
 time.schedule(new TimerTask() 
 @Override
 public void run() 
 if (lastLocation != null) 
 double lat = (double) lastLocation.getLatitude();
 double lot = (double) lastLocation.getLongitude();
 int successFlg = Server.instance.updateLocationInServer(lat, lot, System.currentTimeMillis(), true);
 
 
 , 30000, delay);
 


@Override
public void locationUpdated(Location location) 
 lastLocation = location;


@Override
public void providerStateChanged(int newState)

This is an exception from writing to an encrypted storage. It's thrown by the cypher code. It's unclear why this failed or due to what action but it might be related to logging.
