      PullImageCommand.isImagePulled() calls
      List<Image> images = client.listImagesCmd().withFilters(String.format("


      ", fromImage)).exec();

      Syntax wise, it is correct, however, list image currently only accept one filter now, which is dangling (whose value is true or false).
      See https://docs.docker.com/reference/commandline/cli/#filtering_1,
      Also see here for the docker daemon implemenation:

      So the above call with fromImage as the filter simply doesn't do anything, and I have also Eclipse debug out below to prove this. The below debugger output is when it hits breakpoint inside of that function. Note that "fromImage" is "wzheng2310/foo", but the returned result contains only one entry " "tutum/hello-world:latest".
