Knut Anders Hatlen commented on DERBY-4869:
-------------------------------------------
The getObject() methods don't seem to handle NULL values correctly. Take this
code:
ResultSet rs = s.executeQuery("values cast(null as integer)");
rs.next();
System.out.println(rs.getObject(1, Integer.class));
It prints "0", but I think it should have printed "null".
