Please review the changes to the following issue:


The proposed fix is located at:


This RFE is to implement CLDR time zone names fallback mechanism [1]. 
Prior to this fix, time zone names are substituted with English names. 
With this change, it is generated according to the logic defined in TR 
35. Here are the highlight of the changes:

- CLDRConverter has changed to not substitute/invent time zone display
names, except English bundle for compatibility & runtime performance.
- For English bundle, copy over COMPAT's names as before.
- CLDRConverer now parses regionFormat/gmtZeroFormat/exemplarCity

CLDR provider:
- CLDRTimeZoneNameProviderImpl is introduced to generate fallback names
at runtime.
- If COMPAT provider is present, use it also as a fallback, before the
last resort (GMT offset format)
