Answered it myself!

Thus:

fireTableRowsDeleted(row1, row2);

is the correct method to call but it causes a de-selection of row(s) in the
table.  This then fires a selection event to any registered selection
listeners with a row value of -1 (meaning no row selected).  I had not
trapped a -1 and so I was referencing a Vector element with a -1 index and
getting an indexOutOfBounds error.  Oops.
