javax.net.ssl.SSLException durante Amazon S3 Multipart Upload

Question

Sto utilizzando Simpl3r, a simple high level Android API for robust and resumable multipart file uploads using the Amazon S3 service, per caricare file multimediali nel mio bucket.

In alcuni caricamenti, ricevo un errore SSLException. Ecco il codice in cui viene generata l'eccezione:

(La mia classe è una sottoclasse di un IntentService, come per l'esempio Simpl3r)

@Override 
protected void onHandleIntent(Intent intent) { 

    String filePath = intent.getStringExtra(ARG_FILE_PATH); 
    final String s3ObjectKey = intent.getStringExtra(ARG_OBJECT_KEY); 
    File fileToUpload = new File(filePath); 
    String s3BucketName = getString(R.string.s3_bucket); 

    final String msg = "Uploading " + s3ObjectKey + "..."; 

    // create a new uploader for this file 
    uploader = new Uploader(this, s3Client, s3BucketName, s3ObjectKey, fileToUpload); 

    // listen for progress updates and broadcast/notify them appropriately 
    uploader.setProgressListener(new UploadProgressListener() { 
     @Override 
     public void progressChanged(ProgressEvent progressEvent, 
            long bytesUploaded, int percentUploaded) { 

      Notification notification = buildNotification(msg, percentUploaded); 
      nm.notify(NOTIFY_ID_UPLOAD, notification); 
      broadcastState(s3ObjectKey, percentUploaded, msg); 
     } 
    }); 

    // broadcast/notify that our upload is starting 
    Notification notification = buildNotification(msg, 0); 
    nm.notify(NOTIFY_ID_UPLOAD, notification); 
    broadcastState(s3ObjectKey, 0, msg); 

    try { 
     String s3Location = uploader.start(); // initiate the upload 
     broadcastStateDone(s3ObjectKey, s3Location, "File successfully uploaded to " + s3Location); 
    } catch (UploadIterruptedException uie) { 
     broadcastStateError(s3ObjectKey, "User interrupted"); 
    } catch (Exception e) { 
     e.printStackTrace(); 
     broadcastStateError(s3ObjectKey, "Error: " + e.getMessage()); 
    } 
} 

Ecco la traccia dello stack:

L'eccezione non viene catturato dalla mia clausola Exception. Significa che l'app è bloccata in uno stato di "caricamento" che non finisce mai.

Qualche idea?

Quanto impiegano questi caricamenti? Potresti essere resettato?
