I'm using IntelliJ for Java / Spring development and I have an odd issue with it. Sometimes when I start my Spring Boot application I get error message "java.util.MissingResourceException: Can't find bundle for base name views, locale fi". That might appear also while I am using my application not just in start-up. Before I used NetBeans I didn't get that message so I think it might relate to my IDE. Are there any known issues with that? I didn't find anything from internet. It looks like that sometimes Java disappear language (localization) file.
