> The LazyTimestamp.init() code turns into a NULL generator after parsing the
> very first NULL value (or format error).
> The code is as follows
> {code}
> Timestamp t = null;
> if (s.compareTo("NULL") == 0) {
> isNull = true;
> logExceptionMessage(bytes, start, length, "TIMESTAMP");
> } else {
> try {
> t = Timestamp.valueOf(s);
> } catch (IllegalArgumentException e) {
> isNull = true;
> logExceptionMessage(bytes, start, length, "TIMESTAMP");
> }
> }
> {code}
> As might be obvious from the code above, the class does not reset the isNull
> to false when a parse is successful.
> So if by any reason, it is initialized with a NULL value, the
> LazyTimestamp.getObject() will always return NULL for all further rows.
