> Jitrino.OPT arraycopy optimization fails when Class[] array is used
> I found this error while testing japp2004server in -Xem:server mode.
> Here is a minitest to reproduce:
> public class Hello {
>     public static void main( String argv[] ) {
>         Class[] arr1 = new Class[100];
>         arr1[1] = arr1.getClass();
>         Class[] arr2 = new Class[100];
>         System.arraycopy(arr1, 0, arr2, 0, 100);
>         System.out.println(arr2[1]);
>     }
> }
> I will submit fix & regression test soon
