A DESCRIPTION OF THE PROBLEM :
For loop in the following snippet will end at n == 15588, which obviously not greater that Integer.MAX_VALUE. Looks like it is bug of x64 version only. At least on x32 of same version everything works fine.

import java.util.*;

class ForBug {
    public static void main(String[] a) {
        int m = Integer.MAX_VALUE;

        for ( int n = 1; n <= m; n++ ) {
            System.out.println( "Step " + n );
        }
    }
}


REPRODUCIBILITY :
This bug can be reproduced always.
