    Description

      If CDS dump time and runtime have the same modules settings, e.g., we have the same values for the following options between dump time and runtime:

          --module-path
          --upgrade-module-path
          --add-modules
          --limit-modules
          --add-exports
          --add-reads
          --patch-module

      (or, as a simplified case, none of the above options were given in dump time or run time), we can re-use the module graph computed at dump time. I.e., the bootLayer returned by ModuleBootstrap::boot():
