    Description

      This happens after JDK-8295232

      [2.351s][warning][cds,heap] Archive heap points to a static field that may be reinitialized at runtime:
      [2.351s][warning][cds,heap] Field: jdk/internal/util/StaticProperty::JAVA_LOCALE_USE_OLD_ISO_CODES

      [2.351s][warning][cds,heap]
      [2.353s][warning][cds,heap] Scanned 23829 objects. Found 1 case(s) where an object points to a static field that may be reinitialized at runtime.

      ================
      The fix is to add this field to the exception table in src/hotspot/share/cds/cdsHeapVerifier.cpp
