A DESCRIPTION OF THE PROBLEM :
Class: java.net.HttpCookie
Method: private long expiryDate2DeltaSeconds(String dateString)

the method has following implementation:

    SimpleDateFormat df =
        new SimpleDateFormat(NETSCAPE_COOKIE_DATE_FORMAT);
    df.setTimeZone(TimeZone.getTimeZone("GMT"));

so it's using the default Location (in gemany the Locale for germany)

BUT:
the expire attribute for a cookie is given in english or like that:
Sat, ....

this causes the "df.parse(dateString);" in an exception


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use the handling cookie framework in a none US Locale and get a Cookie with an expires value in english format

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
the

        try {
            Date date = df.parse(dateString);
            return (date.getTime() - whenCreated) / 1000;
        } catch (Exception e) {
            return 0;
        }

shouldn't run in exception block
ACTUAL -
the exception block is called, so the method returns the "exception" value

ERROR MESSAGES/STACK TRACES THAT OCCUR :
exception isn't thrown, but the function returns 0 instead of the long value

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
don't know - you made the HttpCookie final

maybe help would be:

SimpleDateFormat df = new SimpleDateFormat(NETSCAPE_COOKIE_DATE_FORMAT, Locale.US);
