I hope you are doing well.
I'm currently working on a project that uses localization via properties files. It would be nice if we could check, that a property that i'm using in my code exists in a properties file. Of course there are many possibilities to implement localization, therefore we cannot have one rule to cover everything. But maybe a rule that covers the most basic usage of resourceManager.getString("bundleName", "propertyName") can serve as a starting point for people to implement their own rules.
