LocalDate.parse("10000-12-31", DateTimeFormatter.ISO_LOCAL_DATE) throws DateTimeParseException

[abhinavrau]

Following test case is failing using the 0.8.1 version of the backport

public class SimpleTest  extends TestCase 
{
    public void testLocalDateWith5DigitYear()
    {
        LocalDate date = LocalDate.parse("10000-12-31",  DateTimeFormatter.ISO_LOCAL_DATE);
        assertEquals(10000, date.getYear());
    }

}

I get the following exception: org.threeten.bp.format.DateTimeParseException: Text '10000-12-31' could not be parsed at index 0

The javadoc for DateTimeFormatter.ISO_LOCAL_DATE states that it supports "Four digits or more for the year".

Is this is a bug? Any workarounds I can use in the meantime?

Thanks

As described in the spec of DateTimeFormatter.ISO_LOCAL_DATE (used by LocalDate.parse) if there are more than 4 digits the sign (+/-) is required.
The java.time API shows the same behavior in SE 8.

Spec says "Four digits or more for the year. Years in the range 0000 to 9999 will be pre-padded by zero to ensure four digits. Years outside that range will have a prefixed positive or negative symbol. "

Closing, as not a bug.
