java.time.period计算间隔天数的问题

代码是这样的：

 LocalDate localDateStart=LocalDate.of(2018,3,1);LocalDate localDateEnd=LocalDate.of(2018,4,2);Period period=Period.between(localDateStart,localDateEnd);long years=period.getYears();long months=period.getMonths();long days=period.getDays();System.out.println("year="+years+",month="+months+",days="+days);//打印结果 year=0,month=1,days=1

修改开始日期到18年2月28号

        LocalDate localDateStart=LocalDate.of(2018,2,28);LocalDate localDateEnd=LocalDate.of(2018,4,2);Period period=Period.between(localDateStart,localDateEnd);long years=period.getYears();long months=period.getMonths();long days=period.getDays();System.out.println("year="+years+",month="+months+",days="+days);//打印结果：  year=0,month=1,days=5

这算是个bug吗？

先记录，未解决。
