ResultSet.getObject casts to incomplete Date

Question

Hi,
I'm using the jdbc driver in java to copy data from an oracle database to a DB2 database.
The solution is a generic one to copy all columns regardless of type (using PreparedStatement.setObject).
Everything works as a charm except that the DATE columns will just contain a date and no time.
After some digging it seems that the ResultSet.getObject method doesn't include the time...I did:
Object value = inRs.getObject(COLUMN_NAME);
Date myDate = (Date) value;
DateFormat myFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String myDateAsString = format.format(myDate);
This will give me just the date without the time, is this the expected behaviour?
getDate and getTimestamp works just fine but I need to use getObject to keep my method generic.
Any ideas?
Thanks

Ok, so I've got a workaround and found the problem.
Object value = inRs.getObject(column.getKey());
if (value != null && value.getClass().getName().equals("java.sql.Date"))
outStatement.setTimestamp(colIndex, inRs.getTimestamp(column.getKey()));
*} else {*
outStatement.setObject(colIndex, value);
getObject erroneously returns a java.sql.Date from the oracle DATE. Is this an error in the jdbc driver?
UPDATE: According to the manual, this is the default behavior of the driver, but it just doesn't seem rational.
See Table 11-2 getObject and getOracleObject Return Types:
