This bug is fixed in the 1.44d7 daily build. Methods that open an image, like IJ.getImage(), now work as expected in "-batch" command line ".js" scripts. The image is not displayed but it can be retrieved by calling WindowManager.getCurrentImage(). ImageJ commands that display multiple images, such as IJ.run(imp, "Split Channels", ""), also work.
