錯誤而Grails領域類中添加日期字段

Question

我有三個類是這樣的：

假日：

包MNM

class Holiday { 
    //Date start 
    //Date end 
    HolidayStatus status 
    String justification 
    static belongsTo = [ user : User ] 
     static constraints = { 
     status(nullable:true) 
     user(nullable:true) 
     //start(nullable:true) 
     //end(nullable:true) 
     } 
} 

用戶：

package mnm 

class User { 
    String login 
    String password 
    static hasMany = [ holidays : Holiday ] 
     static constraints = { 
    } 
} 

HolidayStatus：

package mnm 

class HolidayStatus { 
    String name 
    static belongsTo = [holiday :Holiday ] 
     static constraints = { 
     name(blank:false) 
    } 
} 

我寫了這樣的集成測試：

void testWithBelongsTo() { 
     def user1 = new User(login:"anto", password:"secret") 
     assert user1.save() 
     def holiday1 = new Holiday(justification:"went to trip") 
     assert holiday1.save() 
     user1.addToHolidays(holiday1) 
     assertEquals 1, User.get(user1.id).holidays.size() 
     user1.delete() 
     assertFalse User.exists(user1.id) 
     assertFalse Holiday.exists(holiday1.id) 
    } 

它可以完美運行，測試都通過。當我改變我的Holiday類是這樣的：

class Holiday { 
    Date start 
    Date end 
    HolidayStatus status 
    String justification 
    static belongsTo = [ user : User ] 
     static constraints = { 
     status(nullable:true) 
     user(nullable:true) 
     start(nullable:true) 
     end(nullable:true) 
     } 
} 

（即增加新的領域，即start, end，這是Date類型。）

現在，如果我改變我的測試弄成這個樣子：

void testWithBelongsTo() { 
     def user1 = new User(login:"anto", password:"secret") 
     assert user1.save() 
     def holiday1 = new Holiday(justification:"went to trip", start: new Date("05/01/2010"),end: new Date("05/01/2011")) 
     assert holiday1.save() 
     user1.addToHolidays(holiday1) 
     assertEquals 1, User.get(user1.id).holidays.size() 
     user1.delete() 
     assertFalse User.exists(user1.id) 
     assertFalse Holiday.exists(holiday1.id) 
    } 

我得到這樣的錯誤：

這裏發生了什麼？我犯了什麼錯誤？這導致其他測試甚至失敗！

在此先感謝。
