A DESCRIPTION OF THE PROBLEM :
Calendar.getFirstDayOfWeek() returns 2 (Monday) instead of 1 (Sunday) for the pt_BR Locale.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Any call of getFirstDayOfWeek with a Calendar object just created with the pt_BR locate presents the problem.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
First day is 1
ACTUAL -
First day is 2

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.util.Calendar;
import java.util.Locale;
public class TestCal
{
public static void main(String[] args)
{
Calendar cal = Calendar.getInstance(new Locale("pt", "BR"));
System.out.println("First day is " + cal.getFirstDayOfWeek());
}
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
use cal.getFirstDayOfWeek(1) every time that the pt_BR locale is used.
