> While debugging DRLVM on Windows Intel64 platform I've found that JET operates incorrectly with long values and prevents some benchmarks to pass.
> Here is the test:
> public class Test {
>     public static void main(String[] args) {
>         long a = 0x00100000000L;
>         long b = 0x01010101010L;
>         test(a,b);
>     }
>     static void test( long a, long b ) {
>         System.out.format("a I b = %1$x%n", (a|b) );
>     }
> }
> RI prints:
> a | b = 1110101010
> Harmony (with JET):
> a | b = 10101010
> I think the cause is a problem in JET code generation on Windows Intel64.
