I looked through the updated webrev and it looks much better (and much 
easier to review too).

I assume CLDRLocaleProviderAdapter.metaInfo should be final.

I'm still not sure about CLDRLocaleProviderAdapter throwing UOE when 
iterating over the installed LocaleDataMetaInfo implementations fail. It 
almost feels like it should be an InternalError as it could only mean 
something wrong with the JDK code or something broken in the JDK 
installation. I have the same concern in 
JRELocaleProviderAdapter.createSupportedLocaleString where it would be 
even more difficult to diagnose why non-English locales appear to be 

Typo in JRELocaleProviderAdapter, installede -> installed.

I see Mandy has pointed out the location of the services configuration 
files, it would be good to check into that.

Otherwise I think this looks reasonable, you've addressed the comments I 
had in the original webrev.
