[Bug classpath/23890] New: GregorianCalendar.equals() doesn't account for change-over date differences

[green at redhat dot com]

The following code should print:
true
false

It currently prints:
true
true


import java.util.*;

public class GregorianTest
{
    public static void main (String args[])
    {
        GregorianCalendar gc1 = new GregorianCalendar ();
        GregorianCalendar gc2 = new GregorianCalendar ();

        System.out.println (gc1.equals (gc2));

        gc2.setGregorianChange (new Date (Long.MAX_VALUE));

        System.out.println (gc1.equals (gc2));
    }
}

The library spec does not specifically say how to decide whether or not two of
these things are equal.  However, experiments with Sun's implementation tell us
that the change date is part of the comparison.

The Mauve test gnu.testlet.java.util.GregorianCalendar.equals also tests for 
this.  

Note that GregorianCalendar will need a special hashCode() implementation when
this is fixed!
