I got always after 1-2 minutes the same errorcode and just the client crashes. The Compiler marks always the line 94

I rly dont know why. Here is my code for the client and server: 

1. //Server
   
   
2. import processing.net.*;
3. Server myServer;
4. Client myClient; 
5. String input;
6. float data[];
7. int val = 0;
8. int rad = 20;        // Width of the shape
9. float xpos, ypos;    // Starting position of shape    
10. 
    
11. float xspeed = 5.6;  // Speed of the shape
12. float yspeed = 4.4;  // Speed of the shape
13. 
    
14. int xdirection = 1;  // Left or Right
15. int ydirection = 1;  // Top to Bottom
16. 
    
17. void setup() {
18.   size(600, 400);
19.    noStroke();
20.   frameRate(30);
21.   ellipseMode(RADIUS);
22.   // Set the starting position of the shape
23.   xpos = width/2;
24.   ypos = height/2;
25.   myServer = new Server(this, 9000); 
26. }
27. 
    
28. void draw() {
29.  background(102);
30. 
    
31.   // Update the position of the shape
32.   xpos = xpos + ( xspeed * xdirection );
33.   ypos = ypos + ( yspeed * ydirection );
34.   
35.   // Test to see if the shape exceeds the boundaries of the screen
36.   // If it does, reverse its direction by multiplying by -1
37.   if (xpos > width-rad || xpos < rad) {
38.     xdirection *= -1;
39.   }
40.   if (ypos > height-rad || ypos < rad) {
41.     ydirection *= -1;
42.   }
43.   // Draw the shape
44.   ellipse(xpos, ypos, rad, rad);
45.   myServer.write(xpos + " " + ypos + " " + rad + " " + rad + "\n");
46.  
47.   myClient = myServer.available();
48.   if (myClient != null) {
49.   input = myClient.readString();
50.   data = float(split(input,' '));
51.   print(input);
52.   }
53. }

57. //Client
59. import processing.net.*;

63. float data[];
64. void setup() {

66. noStroke();

78.     stroke(255);

85. 
    
86. 
    
87. 
    
88.   input = input.substring(0, input.indexOf("\n")); // Only up to the newline
89.

92.    
93.
