jdk9 vs. jdk8 : TimeZone getDisplayName(Locale.GERMAN) for TZ=MET

[Baesken, Matthias]

I wonder why the display names for timezone MET changed ( I observed this on Linux and Solaris) when I compare
jdk8 to jdk9 .

The test is very small, it just outputs for Locale.GERMAN  the display name.
With jdk8 we get a translated german timezone name, but not with jdk9  (this is a bit strange because  the jdk9 rsource file
src/jdk.localedata/share/classes/sun/util/resources/ext/TimeZoneNames_de.java
still contains the translation).

Is this intentional  or a bug ?

Best regards, Matthias



TimeZoneTest.java
------------------------
import java.util.TimeZone;
import java.util.Locale;

public class TimeZoneTest {

    public static void main(String[] args)
    {
        TimeZone tz = TimeZone.getDefault();
        // now test for german
        String dng = tz.getDisplayName(Locale.GERMAN);
        System.out.println("timezone display name for Locale.GERMAN " + dng);
    }
}
------------------------

for environment variable TZ=MET  (export TZ=MET) we get :
../output-jdk8/images/j2sdk-image/bin/java  TimeZoneTest
timezone display name for Locale.GERMAN Zentraleuropäische Zeit

../output-jdk9/images/jdk/bin/java  TimeZoneTest
timezone display name for Locale.GERMAN Middle Europe Time
