First of all, thanks for looking into this bug. I believe I filed the 
bug a while ago.

I'm afraid that the fix above is not what I wanted. Your proposed fix - 
fallback to standard name when daylight name is missing, and long name 
when short name is missing.

I think the right fix would be querying a localized name from another 
provide in the provider chain. I think a typical use case of custom 
locale provider is to replace the stock JDK locale data with user's own 
data. My understanding is that this was not available in Java 7, but 
Java 8 can be configured to use a custom provider first, then fallback 
to others (including the stock JDK locale provider).
