  # buildSrc/addExports: temporary --add-exports and --add-reads
  #
+ # NOTE: this is only used for the bundled sdk build. It is needed only
+ # for changes that have been added to module-info.java and are not in
+ # the minimum required boot JDK.
+ #
  # After a promoted jdk build includes the module-info changes associated
  # with a particular fix, we might eventually remove the --add-exports or
  # --add-reads from this file for that fix, after bumping the minimum jdk
  # to that build.
