JDK-4084800 - In calendar class, roll(int,boolean) increments date but not DAY_OF_WEEK field.
Description

Name: diC59631			Date: 09/26/97


GregorianCalendar c = new GregorianCalendar();
loop
	c.roll(GregorianCalendar.DATE,true);
end loop

This does not work over a month boundary.  It
fails to update the month.  (Rolling down does
the same thing.)  Therefore after August 31, we go
to August 1 instead of September 1.

I am using JavaWorkshop 2 and my classpath has 
jdk1.1.4/lib/classes.zip before the
JDK/lib/classes.zip

Comments
EVALUATION User error; the user is confusing the function of Calendar.roll() with Calendar.add(). The javadoc states clearly that Calendar.roll() does NOT change the value of the next larger field; that's why it's called ROLL. -alanl
