I saw FixedDateFormatTest fail when I was in Holland and had switched my
laptop to use the Amsterdam timezone (but perhaps still using Japanese
style date/time formatting).
The test failed with the %d{dd MMM yyyy HH:mm:ss,SSS} (and the %d{DATE})
formats:
The FastDateFormat used in FixedDateFormat gave 02 Nov 2015 08:59:59,002,
where SimpleDateFormat gave 02 11 2015 08:59:59,002.
So with SimpleDateFormat the month formatted in Japanese style (giving "11"
instead of "Nov").
I fixed FixedDateFormatTest by passing Locale.getDefault() to the
SimpleDateFormat constructor.
I am still not 100% sure what happened. Something to do with
DateFormatSymbols?
