Lukasz Lenart updated WW-4810:
------------------------------
    Description: 
< 2.5.11 calling empty locale {{?request_locale="}} results in locale {{en}}

In 2.5.11 calling empty locale {{?request_locale=''}} results in locale object (not null) with property {{languageTag}} set to {{null}} and as {{language}} == {{""}}

NB: it is also interesting to see the different behaviours for

{code}
wget --header="Accept-Language: fff" --no-check-certificate https://localhost:8443/myProject/path
{code}

{code}
"Accept-Language: ff" => Fula language
"Accept-Language: fff" => empty locale
"Accept-Language: ffff" => exception thrown
{code}

This seems to be the standard behaviour of Locale though.
