        // Open the file and get all the bytes.
        CharSequence bytes = new String(Files.readAllBytes(Paths.get(uri)));
        return // the file into a list of Strings.
        Pattern.compile(splitter).splitAsStream(bytes).filter(((Predicate<String>) String::isEmpty).negate()).map(string -> new SharedString(string.toCharArray())).collect(toList());

the class SemverSchemaVersioner method hasMinorVersionChange.
