Hi Jochen,

It is likely that these are caused by the default locale data change to CLDR with 8008577.

Hi,

after fixing some JDK9 related bugs in our build for Groovy we stumbled
over

new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy",
Locale.US).parse("Thu Jan 01 01:00:00 CET 1970")

failing to parse with

java.text.ParseException: Unparseable date: "Thu Jan 01 01:00:00 CET
1970"
    at java.text.DateFormat.parse(DateFormat.java:366)

This happens not with my local machine using jdk1.9.0-ea-b68, but it
does fail on our CI server used revision 0906b79c9df4 for this.

This seems to be the same issue which has already been reported in 8130845.


A second case is this one:

        Locale locale = Locale.UK
        Locale.setDefault locale
        TimeZone.setDefault TimeZone.getTimeZone('Etc/GMT')
        Date d = new Date(0)
        assertEquals '01/01/70',
DateFormat.getDateInstance(DateFormat.SHORT).format(d);

the assert used to work, but now the format changed to print 01/01/1970
instead of 01/01/70. With the same constellation regarding jdk versions.

This is expected, as the short date format for UK in CLDR is "dd/MM/y".
