[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4920) TimeStamp instead of Date Object behind @Temporal(TemporalType.TIMESTAMP)

TimeStamp instead of Date Object behind @Temporal(TemporalType.TIMESTAMP) ------------------------------------------------------------------------- Key: HHH-4920 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4920 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.0-Beta-3 Reporter: Yves Senn As stated in the java api (http://java.sun.com/javase/6/docs/api/java/sql/Timestamp.html) "Due to the differences between the Timestamp class and the java.util.Date class mentioned above, it is recommended that code not view Timestamp values generically as an instance of java.util.Date. The inheritance relationship between Timestamp and java.util.Date really denotes implementation inheritance, and not type inheritance. " A Timestamp object should not be hided by a Date object. Therefore hibernate should no place a Timestamp object behind that. @NotNull @Temporal(TemporalType.TIMESTAMP) private Timestamp createDate; Instead hibernate has to do something like this behind the scences: createDate = new Date(createDateTimestamp.getTime())
