> While working on lazy resolution support in JIT I found the problem that both JET and OPT process 'new' bytecode incorrectly:
> For the test below:
> public class Hello {
>     public static void main(String[] args) {
>         int x = 1;
>         try {
>             new Foo(x=0);
>         } catch (Error e) {
>             System.out.println(x);
>         }
>     }
> }
> class Foo {
>     static {
>         exception();
>     }
>     static void exception() {
>         throw new RuntimeException();
>     }
>     Foo(int x) {
>         System.out.println("FAILED!");
>     }
> }
> RI and interpreter print '0'
> while JET and OPT print '1'
> Disassembly:
>     public static void main(String args[])
>     {
>         int i = 1;
>     //    0    0:iconst_1        
>     //    1    1:istore_1        
>         try
>         {
>             new Foo(i = 0);
>     //    2    2:new             #2   <Class Foo>
>     //    3    5:dup             
>     //    4    6:iconst_0        
>     //    5    7:dup             
>     //    6    8:istore_1

>         }
