java.text.SimpleDateFormat.format(Date n, StringBuffer str, FieldPosition fp) does not
set indexes of FieldPosition object.

Javadoc says about pattern chars:

 * To specify the time format use a time pattern string.
 * In this pattern, all ASCII letters are reserved as pattern letters,
 * which are defined as the following:
 *
 * Symbol Meaning Presentation Example
 * ------ ------- ------------ -------
 * G era designator (Text) AD
 * y year (Number) 1996
 * M month in year (Text & Number) July & 07
 * d day in month (Number) 10
 * h hour in am/pm (1~12) (Number) 12
 * H hour in day (0~23) (Number) 0
 * m minute in hour (Number) 30
 * s second in minute (Number) 55
 * S millisecond (Number) 978
 * E day in week (Text) Tuesday
 * D day in year (Number) 189
 * F day of week in month (Number) 2 (2nd Wed in July)
 * w week in year (Number) 27
 * W week in month (Number) 2
 * a am/pm marker (Text) PM
 * k hour in day (1~24) (Number) 24
 * K hour in am/pm (0~11) (Number) 0
 * z time zone (Text) Pacific Standard Time
 * ' escape for text
 * '' single quote
 
It means the character 'z' corresponds the TIMEZONE_FIELD.

Here is the test demonstrating the bug:

-----------------Test.java------------------------
import java.text.*;
import java.util.*;

public class TestDE {
    public static void main (String args[]){
        SimpleDateFormat sdf = new SimpleDateFormat("z", Locale.US);
        FieldPosition fp = new FieldPosition(DateFormat.TIMEZONE_FIELD);
        System.out.println(sdf.format(new Date(9234567890), new StringBuffer(""), fp));
        System.out.println("beginIndex = " + fp.getBeginIndex());
        System.out.println("endIndex = " + fp.getEndIndex());
    }
}

---------Output from the test---------------------
PST
beginIndex = 0
endIndex = 0
