In Java 8 you could easily turn your text file into a List of Strings with streams by using Files.lines and collect:

    } catch (URISyntaxException e) {
        LOGGER.error("Failed to load file.", e);
    }
    List list = null;
    try (Stream lines = Files.lines(Paths.get(uri))) {
        list = lines.collect(Collectors.toList());
    } catch (IOException e) {
        LOGGER.error("Failed to load file.", e);
    }
    return list;
}
