Steps to reproduce:
- configure preferred locales in Chrome like: hu, en, en-US, fr
- try to access the server config page, like http://aldaris.sch.bme.hu:8080/openam/XUI/#deployment/servers/01/general
Notice that the page is in French instead of English.
It looks like that this is because that there are no explicit _en localization files available, and #getBundleInPreferredLocale will skip over the "en" locale because of that resulting in displaying French text.
