JDBC getRow returns 0 after first instead of 1

I think the JDBC driver has several bugs around ResultSet row
numbering. According to the JDBC API docs[1] the getRow() method on
ResultSet should return 1 for the first row. Currently it returns zero.

i.e.     if (rs.first())         int n = rs.getRow();  // n is now 0 instead of 1
The same problem exists with the absolute and related methods which
need to be passed 0 to go to the first row but the API docs say it should
be 1.

If I'm wrong could someone please explain what I got wrong.

PS, 
Where is the CVS archive for the sources and is there anon access? I could
not find it on the postgresql.org site.
