is that rs.next() should return false (indicating that there is not a 'next'
row).

Wrong. As a lot of others already stated, there is always a result to
agregate functions. NULL if necessary.

If you consider this a bug, what would you expect from the same query if
there were rows, but every row had an NULL in PK_SN? [I see, you ment PK_SN
to be an primary key (and therefor NOT NULL), but just imagine.]
