Thrown by {@link Cursor#putCurrent Cursor.putCurrent} if the old and newdata are not equal according to the configured duplicate comparator or default comparator.

If the old and new data are unequal according to the comparator, this would change the sort order of the record, which would change the cursor position, and this is not allowed. To change the sort order of a record, delete it and then re-insert it.
