      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.
