A DESCRIPTION OF THE PROBLEM :
DateFormatSymbols.getShortMonths should give short month names (Jan vs. the longer January), but in the Finnish locale ("fi, "FI") it gives the long month name in a strange format:
"January" in Finnish is "tammikuu",
the short month name "Jan" is "tammi",
but instead that Java 8 returns "tammikuuta", which means approximately "of January" and is usable when formatting dates like "1st of January".

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run this snippet:

import java.util.Locale;
import java.text.DateFormatSymbols;

public class Test {
    public static void main(String [] args) {
        System.out.println(new DateFormatSymbols(new Locale("fi", "FI")).getShortMonths()[0]);
    }
}


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
In Java 7, the result is "tammi".
ACTUAL -
