    The JVM doesn't really have global variables. The closest thing to them are public static variables, which isn't really the same thing.

    Whether or not you have to add a mutex depends on what you want to do with the variables. In general, the answer is "no", but that is in part because in general you wouldn't want to have mutable public static variables.
