java.text.NumberFormat.equals(Object) method doesn't work correctly.

The java.text.NumberFormat.equals() method does not work correctly.
This method should return false if two objects are different.
But it ignores setting of GroupingUsed flag.

Here is the test demonstrating the bug:

-----------------NumberFormatEqualsTest.java------------------------
import java.text.*;

public class NumberFormatEqualsTest {
  
  public static void main(String args[]) {
    
    NumberFormatTest nf1 = new NumberFormatTest();
    NumberFormatTest nf2 = new NumberFormatTest();
    
    nf1.setGroupingUsed(false);
    nf2.setGroupingUsed(true);
  
    if (nf1.equals(nf2)) System.out.println("Test failed");
    return;
  }
}


  // implementation of abstract method of the NumberFormat class

class NumberFormatTest extends NumberFormat {
   public StringBuffer format(double number,
                        StringBuffer toAppendTo,
                        FieldPosition pos) {
      return new StringBuffer("");
    }
    public StringBuffer format(long number,
                        StringBuffer toAppendTo,
                        FieldPosition pos) {
      return new StringBuffer("");
    }
    public Number parse(String text, ParsePosition parsePosition) {
      return new Integer(0);
    }
}
