Need help spotting an error in my code regarding reading a matrix through a buffer

this is an homework question but I have been working at it for quite a while and I must be getting slightly blind so I would really appreciate help spotting an error.

public class Maze {

    int[][] grid;
    private final int TRIED = 2;
    private final int PATH = 3;

    public Maze(String fileName) throws IOException {
        BufferedReader in = new BufferedReader(new FileReader(fileName));
        String s;
        String [] aux= new String [2];
        int x=0; 

        aux=in.readLine().split("\\s*[, .]\\s*");
        int dimensao=Integer.parseInt(aux[0]);
        String [][] gridString= new String [dimensao][dimensao];
        grid= new int[dimensao][dimensao];

         while ((s=in.readLine())!=null){
            gridString [x]=s.split("\\s*[,.]\\s*");
            x++;
            System.out.println(s);
        }
         System.out.println();
        for (int i=0;i<gridString.length;i++){
            for(int j=0;j<gridString[0].length;j++){
                System.out.print(gridString[i][j]+" ");
                switch (gridString[i][j]) {
                    case "true":
                        grid[i][j]=1;
                        break;
                    case "false":
                        grid[i][j]=0;
                        break;
                }
            }            
            System.out.println();
            }
        for (int i=0;i<grid.length;i++){
            for(int j=0;j<grid[0].length;j++){
                System.out.print(grid[i][j]);
            }
            System.out.println();
        }           
    }

and in another class class I invoke it using this an input:

 5 

true, false, true, false, false 

true, false, true, true, true 

false, false, false, false, true

true, true, false, true, true

false, false, false, true, false

The goal is to convert into an integer matrix with "true" being represented by 1 and "false" being 0. Things is my output is this 

10100

10110

00000

11010

00010

And I just cant figure out what happened to the "true" values on tha last column.

I think it might be the missing space in the second split - maybe reading in as " true"
