死循环为什么程序不走进不去，现在这么智能了么？

Question

StringBuffer sb = new StringBuffer();
    for(int i=0;i<128;i++){
        sb.append("tttttttt");
    }
    StorageInfo info;
    String txt;
    double i = Double.MAX_VALUE;
    while(i!=i){
        info =getMemoryInfo();
        txt =info.available.substring(0,5);
        info.toLog();
        if(Double.parseDouble(txt)>0.01) {
            if (WRITEENABLE) {
                WriteTxtFile(sb.toString());
            } else {
                break;
            }
        }
        else{
            break;
        }
    }
