I have a globalGraphics variable.

Declaration:
private Graphics globalGraphics;
Initialization(see in paint()):
globalGraphics = g.create();

draw(globalGraphics);

public void run() {
while (true) {
GenerateDefaultSnake();
move();
draw(globalGraphics);
repaint();

try
{
Thread.currentThread();

Ok so now the problem is with the draw method:
public void draw(Graphics g)
{
g.clearRect(0, 0, BOX_WIDTH * GRID_WIDTH + 10, BOX_HEIGHT * GRID_HEIGHT + 20);

BufferedImage buffer = new...

public void paint(Graphics g)
{
this.setPreferredSize(new Dimension(640, 480));
GenerateDefaultSnake();
PlaceFruit();
globalGraphics = g.create();
this.addKeyListener(this);
if...

Same thing hapens

So line 85 is:
Point head = snake.peekFirst();

private LinkedList<Point> snake;
