A DESCRIPTION OF THE PROBLEM :
the int variable change in the while loop, then output the result is wrong.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the example code.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
always output "-1".
ACTUAL -
after a lot of loop, output the "/".

---------- BEGIN SOURCE ----------
public class WhileLoopTest {
  public void test1() {
    int i = 8;
    while ((i -= 3) > 0) ;
    System.out.println("i = " + i);

  }

  public static void main(String[] args) {
    WhileLoopTest tst = new WhileLoopTest();
    for (int i = 0; i < 50_000; i++) {
      tst.test1();
    }
  }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
just disable jit or use the AtomInteger.

  public void test2() {
    AtomicInteger i = new AtomicInteger(8);
    while ((i.addAndGet(-3)) > 0) ;
    System.out.println("i = " + i.intValue());
  }

FREQUENCY : always
