it seems that the result of CopyMatrixtoArray() change the "char" values (0-255) to something signed... (but not CopyVectortoArray())

The picture attached below shows what happens, testing for the color of somes pixels : 

-with the CopyMatrixtoArray() method in the first tens lines of the max window, 

-and with the CopyVectortoArray() method in the tens lines after.

bug-copymatrixtoarray-is-signed-instead-of-char

here is the java code and the patch to reproduice :

public class testttttttttt extends MaxObject {

        declareInlets(new int[]{DataTypes.ALL});

        declareOutlets(new int[]{DataTypes.ALL,DataTypes.ALL,DataTypes.ALL,

            DataTypes.ALL,DataTypes.ALL,DataTypes.ALL,DataTypes.ALL,DataTypes.ALL});

    JitterMatrix jm = new JitterMatrix();

        int planecount = jm.getPlanecount();

        int offset[] = new int[]{0,0};

        int row[] = new int[dim[0]*planecount*dim[1]];

        // jm.copyVectorToArray(0, offset, row, dim[0]*planecount*dim[1], 0);

        jm.copyMatrixToArray(row);

        outlet(0, "ARRAY : ", row );

        outlet(0, "FIRST ROW : ");

        outlet(0, "test white :", new int[]{ row[1] , row[2],row[3] } );

        outlet(0, "test red :", new int[]{ row[33] , row[34],row[35] } );

        outlet(0, "test blue :", new int[]{ row[37] , row[38],row[39] } );

        outlet(0, "test magenta", new int[]{ row[29] , row[30],row[31] } );

        outlet(0, "EIGHTH ROW : ");

        outlet(0, "test blue :", new int[]{ row[281] , row[282],row[283] } );

        outlet(0, "test blue :", new int[]{ row[285] , row[286],row[287] } );

        outlet(0, "test black :", new int[]{ row[289] , row[290],row[291] } );

[BUG] CopyMatrixtoArray is signed instead of "char"
