From description of replace method:

replace: Removes a field from this Manager and replaces it with
another field. The specified oldField must be a direct child of this
manager and the specified newField must not be being managed by any
Manager, including this one.

Here you are substituting bitmapField to other ones more than once to the same Manager:

              hfm.replace(bitmapField2, bitmapField);
              hfm.replace(bitmapField3, bitmapField);
              hfm.replace(bitmapField4, bitmapField);
              hfm.replace(bitmapField5, bitmapField);
