Tutorial Code Problem

Hi. I have this .txt file, exported from grasshopper. I am trying to use PVectore to split data in txt file and make a spiderweb from that, but I see error "array index out of bounds:1" in line 26. Anybody knows what is wrong with this code?

This is the code:

        import peasy.*;
        PVector GHpoints[] = new PVector[100];
        PeasyCam cam;
        PVector[] jumpersB;

        void setup() {
          size (600,600,P3D);
        cam = new PeasyCam(this, 100);
        cam.setMinimumDistance(5);
        cam.setMaximumDistance(20);
          smooth ();
          frameRate(100);
        }

        void draw(){
          background (255);
          import_GH();
          spiderWeb();
        }

        void import_GH(){
         String GH_PT[]=loadStrings("GH_PT.txt");
         for (int x=GH_PT.length-1; x>=0; x--){
        float point[] = float(split(GH_PT[x], ' '));
           PVector Temp_PT = new PVector(point[0], point[1], point[2]);
           GHpoints[x] = Temp_PT;
           }}

        void spiderWeb(){


        for (int i=0; i<GHpoints.length-1; i++){
          for (int b=0; b<GHpoints.length-1; b++){
        if( jumpersB[i] != null){
          if( jumpersB[b] != null){

        PVector locA = jumpersB[i]; PVector locB = jumpersB[b];

        float distance = PVector.dist(locA, locB);
        if ((distance > 0) && (distance < 3)) {
        stroke(100, 110);

        strokeWeight(1);

        line(locA.x, locA.y, locA.z, locB.x, locB.y, locB.z);

        }}}}}}
