SimpleDateFormat.parse返回errorIndex为0

Question

Using jdk1.7.0_55, I'm getting parseposition.errorIndex as 0 in case of timezone is not standard one.

But using jdk1.6.0_38 I'm getting parseposition.errorIndex as 21 for the same wrong timezone format

Below is the sample:

String date = "13 Jan 2005 21:45:34 ABC";
String format = "dd MMM yyyy HH:mm:ss z";
ParsePosition pp = new ParsePosition(0);
pp.setIndex(0);
SimpleDateFormat sd = new SimpleDateFormat(format,Locale.ENGLISH);
Date d = sd.parse(date,pp);
System.out.println("Error Index "+pp.getErrorIndex());

Result Using jdk 6:

Error Index 21

Result Using jdk 7

Error Index 0

Why there is difference in it?

Please help

Indeed this is a regression. Still broken in latest Java 8 build. Public OpenJDK bug tracker does not list it, so I have reported it to Oracle for review. It is tracked by Oracle with Review ID: JI-9021556

Unfortunately there is no way for you to fix that.
