<i18n dev> Code Review for JDK-8141243: Unexpected timezone returned after parsing a date

[Masayoshi Okutsu]

Hi Ramanand,

I don't think this fix is correct. This change mixes up time zone IDs 
and display names. SimpleDateFomat should parse only display names.

There's no perfect solution on the issue because the short display names 
(abbreviations) can't be unique. So, I'd suggest that the UTC display 
names in all resource bundles (all TimeZoneNames*.java under 
sun.util.resources) move up to the compatibility group.

BTW, the symptom is reproducible in JDK 9 with the legacy time zone 
names (run java with -Djava.locale.providers=COMPAT). So, the fix should 
be done in JDK 9 first.

Thanks,
Masayoshi
