A DESCRIPTION OF THE PROBLEM :
value = 7. returns all 6s in the buffer

public int[][] xyz(int value){
int[][] buff = new int[value][value];
for (int z=0; z <value; z++)
for (int y=0; y <value; y++)
for (int x=0; x <value; x++){
buff[x][y] = z;
};
return buff;
}

REGRESSION : Last worked in version 8u231

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
public int[][] xyz(int value){
int[][] buff = new int[value][value];
for (int z=0; z <value; z++)
for (int y=0; y <value; y++)
for (int x=0; x <value; x++){
buff[x][y] = z;
};
return buff;
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A tensor of 0 to 6
ACTUAL -
returns all 6s in the buffer

CUSTOMER SUBMITTED WORKAROUND :
Still looking for one. I've been experimenting with different permutations of the issue. for instance, if I use z-- it produces
