CachedRowSetImpl.updateObject ignores the scale

SonarCloud reports the following problem:
  The return value of "setScale" must be used.

    public void updateObject(int columnIndex, Object x, int scale) throws SQLException {
        // sanity check.
        checkIndex(columnIndex);
        // make sure the cursor is on a valid row
        checkCursor();

        int type = RowSetMD.getColumnType(columnIndex);
        if (type == Types.DECIMAL || type == Types.NUMERIC) {
            ((java.math.BigDecimal)x).setScale(scale); // <--- here
        }
        getCurrentRow().setColumnObject(columnIndex, x);
    }

BigDecimal.setScale returns the updated BigDecimal, and it should be used instead. I.e. with:
   x = ((java.math.BigDecimal)x).setScale(scale);

This bug predates OpenJDK history.
