Buggy source:

Fixed version (ground truth):

      temConnection.setUiSchema(((DatabaseConnection)iMetadataConnection.getCurrentConnection()).getUiSchema());
    }
    if (((DatabaseConnection)iMetadataConnection.getCurrentConnection()).getSID() != null) {
      temConnection.setSID(((DatabaseConnection)iMetadataConnection.getCurrentConnection()).getSID());
    }
