Hi Naoto,

Logging uses:

ZonedDateTime zdt = ZonedDateTime.ofInstant(
                 record.getInstant(), ZoneId.systemDefault());

and then

String.format("%1$tb %1$td, %1$tY %1$tl:%1$tM:%1$tS %1$Tp %2$s%n%4$s: 
%5$s%6$s%n", ...)

to format the date.

If the locale provider can't be loaded, is that going to cause problem,
when logging is invoked to log the info/warning?

In particular:

  198                             .log(Logger.Level.INFO, e);
  199                     adapterInstances.putIfAbsent(type, 
  200                     if (defaultLocaleProviderAdapter == type) {
  201                         defaultLocaleProviderAdapter = Type.FALLBACK;
  202                     }

Maybe logging should only be invoked *after* lines 199-202?

Same potential issue in

lines 367-372

best regards,
