Date format not recognized on date 1/1/70

When I insert the date 1/1/70 in the DateField by keyboard, I’ve got the following error: “Date format not recognized”, if I insert the same date using the date picker and mouse, it’s ok.

You can test this on your Vaadin Sampler site, on date field page using Day resolution.

For me the sampler works. What Locale are you using in your own sample? Are you using some custom date format?

I just use a DateField with all defaults settings, I just change the resolution.

I made this video for examplify:

Anyone with a workaround?

I tested with Vaadin 8 a still happens!

I just notice that this only happens if I have my computer in UTC timezome.

I have opened a
