OBJLoader gives error when trying to load high poly models

Question

I made a OBJFILELoader but when i try to load a high poly model it gives me a empty string error I Checked the file and it seems to be totally fine Im not really sure if the problem is with the code or with the model because it dosent work on any high poly model The Empty string error is at Vector3f vertex = new Vector3f(Float.parseFloat(currentLine[1]) (Line 45) `

public static ModelData loadOBJ(String objFileName) {
        FileReader isr = null;
        File objFile = new File(RES_LOC + objFileName + ".obj");
        try {
            isr = new FileReader(objFile);
        } catch (FileNotFoundException e) {
            System.err.println("File not found in res; don't use any extention");
        }
        BufferedReader reader = new BufferedReader(isr);
        String line;
        List<Vertex> vertices = new ArrayList<Vertex>();
        List<Vector2f> textures = new ArrayList<Vector2f>();
        List<Vector3f> normals = new ArrayList<Vector3f>();
        List<Integer> indices = new ArrayList<Integer>();
        try {
            while (true) {
                line = reader.readLine();
                if (line.startsWith("v ")) {
                    String[] currentLine = line.split(" ");
                                        System.out.println(currentLine[1]);
                                        System.out.println("^");
                    Vector3f vertex = new Vector3f((float) Float.valueOf(currentLine[1]),
                            (float) Float.valueOf(currentLine[2]),
                            (float) Float.valueOf(currentLine[3]));
                    Vertex newVertex = new Vertex(vertices.size(), vertex);
                    vertices.add(newVertex);

                } else if (line.startsWith("vt ")) {
                    String[] currentLine = line.split(" ");
                    Vector2f texture = new Vector2f((float) Float.valueOf(currentLine[1]),
                            (float) Float.valueOf(currentLine[2]));
                    textures.add(texture);
                } else if (line.startsWith("vn ")) {
                    String[] currentLine = line.split(" ");
                    Vector3f normal = new Vector3f((float) Float.valueOf(currentLine[1]),
                            (float) Float.valueOf(currentLine[2]),
                            (float) Float.valueOf(currentLine[3]));
                    normals.add(normal);
                } else if (line.startsWith("f ")) {
                    break;
                }
            }
            while (line != null && line.startsWith("f ")) {
                String[] currentLine = line.split(" ");
                String[] vertex1 = currentLine[1].split("/");
                String[] vertex2 = currentLine[2].split("/");
                String[] vertex3 = currentLine[3].split("/");
                processVertex(vertex1, vertices, indices);
                processVertex(vertex2, vertices, indices);
                processVertex(vertex3, vertices, indices);
                line = reader.readLine();
            }
            reader.close();
        } catch (IOException e) {
            System.err.println("Error reading the file");
        }
        removeUnusedVertices(vertices);
        float[] verticesArray = new float[vertices.size() * 3];
        float[] texturesArray = new float[vertices.size() * 2];
        float[] normalsArray = new float[vertices.size() * 3];
        float furthest = convertDataToArrays(vertices, textures, normals, verticesArray,
                texturesArray, normalsArray);
        int[] indicesArray = convertIndicesListToArray(indices);
        ModelData data = new ModelData(verticesArray, texturesArray, normalsArray, indicesArray,
                furthest);
        return data;
    }

`

I checked the file its totally fine I checked the String its also fine I tried using other models And it seems to work as long as they are not high poly
