The web console now supports localization. Unfortunately the Bundles plugin is limited only to localization of the plugin. It can and should display localized bundle names and manifest headers.
The attached patch updates it to use Bundle.getHeaders(locale) instead of Bundle.getHeaders()
The locale is always taken from the HTTP request.
The only exception is when printing the configuration. In this case Locale.ENGLISH is used - the printed configuration can be used mostly by developers and support engineers, so English is better than any other.
