Spring When Accept-Language header is blank, the default locale should be returned

Sending such a request header with an "empty text" value is I think invalid HTTP. Can you name an HTTP client that does this?

I don't think this is a common case.

Is there a case where this change would be useful?

I think what you said is correct. However, sometimes the "accept_language" is manually added by the front-end colleagues. If they don't include this, I expect the return value to be the default value that I have set, rather than the default language of the machine.

Of course, this is just my suggestion. I've already overridden this class locally to solve this problem.

Thanks for letting us know. Let's consider this an invalid usage right now.
