While this may be true or not (the mechanism of having proper environment variables set is just made to have different users running the same programs with different locales), I don't think the problem is here. The real issue is that the Locale class seems to be unable to correctly detect the default locale. Of course, given that the Java locale infrastructure isn't able to discriminate between different scopes of a locale (that is, there is nothing like the different LC_* variables), I'm not expecting it to actually display messages in a language and sorting strings or showing numbers according to a different locale. But the algorithm to detect the current default locale seems to be a little strange (I'm using the small program written by David): > [12:12] giova...@edelstein:/tmp$ export | grep LC > [12:12] giova...@edelstein:/tmp$ export | grep LANG > declare -x GDM_LANG="it_IT.utf8" > declare -x LANG="it_IT.utf8" > [12:12] giova...@edelstein:/tmp$ java LocaleTest > Language, Country, Variant, Name > > Default locale: > it, IT, , , italiano (Italia) > [12:13] giova...@edelstein:/tmp$ LC_CTYPE=de_DE.UTF-8 java LocaleTest > Language, Country, Variant, Name > > Default locale: > de, DE, , , Deutsch (Deutschland) > [12:13] giova...@edelstein:/tmp$ LC_MESSAGES=de_DE.UTF-8 java LocaleTest > Language, Country, Variant, Name > > Default locale: > it, IT, , , italiano (Italia) Why does LC_TYPE have influence over the the default locale and LC_MESSAGES (or any other LC_* variable) not? Anyway, this seems to be a really minor issue to me. Nonetheless it's something strange! > It is the applications responsibility to provide a preference for > choosing the locale. Maybe, but anyway the JVM should be able to correctly detect the default locale when this isn't done. BTW, I think that the workaround for josm can be just clearing LC_CTYPE then firing the JVM.
