> While debugging DRLVM on WIN64 platform I've found that Double.doubleToLongBits(double) method produces incorect results and prevents some benchmarks to pass.
> Here is the test:
>     public static void main(String[] args) {
>         System.out.println(Double.doubleToLongBits(1));
>     }
> RI prints:
> 4607182418800017408
> Harmony (both JET and OPT)
> -3689348814741910324
> I think the cause is a problem in native stubs and calling conventions on windows in DRLVM.
