      Description

      ADDITIONAL SYSTEM INFORMATION :
      Windows 10 / OpenJDK 11.0.1

      A DESCRIPTION OF THE PROBLEM :
      CLDRCalendarDataProviderImpl seems to have some bug that is logged on CONFIG level which maps to INFO level when one uses the SLF4J bridge for JUL.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Start a JShell and execute the snippet given below

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      No log output about things that should not happen
      ACTUAL -

      $14 ==> java.text.SimpleDateFormat@5a0f0632

      The four log lines are:
      * once for current locale `"en"`, key `"firstDayOfWeek"`
      * once for current locale `""`, key `"firstDayOfWeek"`
      * once for current locale `"en"`, key `"minimalDaysInFirstWeek"`
      * once for current locale `""`, key `"minimalDaysInFirstWeek"`
      in sun.util.locale.provider.LocaleServiceProviderPool#getLocalizedObjectImpl

      My guess is that maybe this commit causes the issue: http://hg.openjdk.java.net/jdk/jdk/rev/57148c79bd75
