I am trying to run following code on emulator (it's an interview
puzzle with deliberate racing condition) and I observe all threads
stuck on the first x++ and join() never executed.
If I comment out x++ everything comes to completion...
Is it something I do wrong or static access on dalvik-emulator is
broken somehow?
Should I file a bug?
I have the latest sdk update for the time of writing:
static {
try {
test();
} catch (InterruptedException e) {
throw new Error(e);
}
}
static int x;
public static void test() throws InterruptedException {
Thread[] t = new Thread[5];
for (int i = 0; i < 5; i++) {
final int k = i;
t[i] = new Thread() {
public void run() {
for (int j = 0; j < 5; j++) {
x++;
}
System.out.println("done[" + k + "]");
}
};
t[i].start();
}
for (int i = 0; i < 5; i++) {
t[i].join();
}
System.out.println("x=" + x);
}
