        txnHelper.setForceWritable(true);
        boolean requiresNew = false;
        if (AlfrescoTransactionSupport.getTransactionReadState() != TxnReadState.TXN_READ_WRITE)
        {
            
            requiresNew = true;
        }
        txnHelper.doInTransaction(new RetryingTransactionCallback<Object>()
        {

            @Override
            public Object execute() throws Throwable
            {
          try { 
             this.serviceRegistry.getNodeService().addAspect(options.getSourceNodeRef(), 
                IcmrModel.ASPECT_ENCRYPTED_CONTENT, null);
             } catch (Exception e) {
             log.error("Unexpected error", e);
             }
            }
    
        }, false, requiresNew);
