"Vector<Vector>" isn't the same as "Vector<? extends Vector>"

(despite the theory, I tried anyway, and got the expected 
error that Vector<TestVectorSubclass> is indeed not convertible
to Vector<Vector>)


Patrick's advice to use AbstractTableModel already solved that
one for me.

PS:
Some comment for private method "justifyRows" of DefaultTableModel
that I noticed only in the course of changing to AbstractTableModel
reveals developers' intention:
"       // Sometimes the DefaultTableModel is subclassed
"       // instead of the AbstractTableModel by mistake.
Yep, I was guilty of that - fixed now in my code.
