is Symlink Java 
try {
    Object path = File.class.getMethod("toPath").invoke(file);
    return (Boolean) Class.forName("java.nio.file.Files")
            .getMethod("isSymbolicLink", Class.forName("java.nio.file.Path")).invoke(null, path);
} catch (NoSuchMethodException x) {

voidmakeSymLink(File target, File destination)
Make a link

Make a link using the system's ``ln`` command. 

if (!Files.exists(destination.toPath())) {
    Files.createSymbolicLink(destination.toPath(), target.toPath());
FilereadSymbolicLink(@Nonnull File symlink)
Reads the target of the symbolic link 
final java.nio.file.Path path = java.nio.file.Files.readSymbolicLink(symlink.toPath());
return path.toFile();
StringreadSymlinkTarget(File file)
read Symlink Target 
try {
    return Files.readSymbolicLink(Paths.get(file.getAbsolutePath())).toString();
} catch (IOException e) {
    return null;
FileresolveSymbolicLink(File file)
resolve Symbolic Link 
Path path = file.toPath();
return Files.isSymbolicLink(path) ? Files.readSymbolicLink(path).toFile() : file;
StringsanitizeUrl(String link)
Make sure an URL is "portable", in that it doesn't contain bad characters that break the open command in some OSes. 
link = link.trim();
if (link.startsWith("\\url{") && link.endsWith("}")) {
    link = link.substring(5, link.length() - 1);
link = link.replaceAll("\\+", "%2B");
try {
    link = URLDecoder.decode(link, StandardCharsets.UTF_8.name());
} catch (UnsupportedEncodingException ignored) {
