Default Hessian deserialization chokes on java.sql.Date/Timestamp/Time

When using fields of type java.sql.Date/Timestamp/Time with Hessian 4.0.7, I noticed that null values are not handled gracefully during deserialization. Is there a deeper reason for this or is it an implementation error? Detailed stack trace follows:
