for loop terminating early when comparing to Integer.MAX_VALUE and using System.out.println

Question

When I run this class the for loop seems to terminate early

class Test {

    public static void main(String[] args) {
        int result = 0;
        int en         


        

Answer 1

Its a known bug in Java 6. The JIT optimizes the loop incorrectly. I believe more recent versions of Java don't have this bug.

Java 6 update 16 is just over two years old. I suggest you update to the latest version Java 6 update 25 if you can't update to Java 7.

BTW Java 6 will be End Of Free Support in a couple of months (Dec 2012)

Answer 2

You can work around the JVM bug by using Integer.MAX_VALUE-1.
