Strange behaviour of "=" and "++"

[Omer Haderi]

    
for (int i = 0; i < 2; ) {
System.out.println(i);
i = i++;             // line #1
System.out.println(i);
break;                //line #2
}

When I saw this snippet I was totally sure that the output was: 0 1

But it is: 0 0
if we remove line #2 then it will print zeros for ever.

I know that "=" has higher precedence so in line #1 the assignment take place first (so i = 0) and then the post increment (so i becomes 1) but the output is zero

does anyone have any hint ?
