Datepicker shows incorrect year when only 2 year digits are entered calendar is expanded

[prithvipatil]

Issue can be simulated using nachocalendar-demo-0.23.jar.

If you manually enter only last 2 digits of year into the DateField and if you click on down arror to expand the calendar:

• When year value is <=42, Popup shows years starting with 20xx. Where xx is the 2 digit year value you had entered manually.
• When year value is >=43, Popup shows years starting with 19xx. Where xx is the 2 digit year value you had entered manually.

Please refer to the attached GIF file for the simulation of the issue.

What can be done to fix this behavior? I expect DateField to always shows years starting with 20xx.
