Description:
I get an deserialization exception when a specify an empty tag for a date field. I looked at the source code and think I have found the problem - 
 
The parse creates an empty string for the empty tag. But the deserializer doesn't take that into account. 

class org.apache.axis.encoding.ser.CalendarDeserializer
************
 public Object makeValue(String source) {^M
        Calendar calendar = Calendar.getInstance();^M
        Date date;^M
        boolean bc = false;^M
^M
        // validate fixed portion of format^M
        if ( source != null ) {^M
            if (source.charAt(0) == '+')^M
                source = source.substring(1);^M
^M
            if (source.charAt(0) == '-') {^M
                source = source.substring(1);^M
                bc = true;^M
            }^M
^M
