code: @Deprecated
      public void load(Job job, Constructor<R> cons) {
          this.cons = cons;
          initBaseDir(job.getBuildDir());
      }
docs: Backward compatibility method that notifies {@link RunMap} of who the owner is.
  
  Traditionally, this method blocked and loaded all the build records on the disk,
  but now all the actual loading happens lazily.
  
  @param job
  Job that owns this map.
  @param cons
  Used to create new instance of {@link Run}.
  @deprecated as of 1.485
  Use {@link #RunMap(File, Constructor)}
