Fallback locale should be ROOT, and not Locale.getDefault() ----------------------------------------------------------- Key: WFLY-4228 URL: https://issues.jboss.org/browse/WFLY-4228 Project: WildFly Issue Type: Enhancement Components: CLI, ConfigAdmin Affects Versions: 9.0.0.Alpha1 Environment: Any system with default locale set to something diffirent from english Reporter: Romain Pelisse Assignee: Romain Pelisse Priority: Minor While investigating WFLY-3723, I found out that when a bundle for a specified locale can not be found, Wildfly code fallbacks to Locale.getDefault, rather than use the Locale.ROOT. This is a side effect on non-english system, because there is no bundle for "en_US", and root should be used in this case. I proposed to fix it by replacing all relevant occurences of Locale.getDefault() by Locale.ROOT.
