RFR: 8152817: Locale data loading fails silently when running with a security manager

[Masayoshi Okutsu]

Hello,

Please review the fix for JDK-8152817. The fix is to load locale data 
from its own module without calling 
ResourceBundleProviderSupport.loadResourceBundle.

I changed the synopsis of the JBS issue because it's a general issue of 
loading locale data under a security manager, and the regression test 
uses DateFormatSymbols.

Issue:

Thanks,
