>          Issue Type: Bug
>          Components: Javaflow
>    Affects Versions: CSV 1.0
>         Environment: Debian linux using Sun JDK 1.6 and asm 4.0_RC2
>            Reporter: Raji Sankar

>  I have a fn which has a code as below:
> private void callsomeshared()
>         throws Exception
> {
>         Method mthd = _someShared.getDeclaredMethod("doSomething");
>         int cnt = 0;
>         while (cnt < 10)
>         {
>             mthd.invoke(_shared);
>             //Continuation.suspend();
>             cnt++;
>         }
> }
> The doSomething does this:
>     public boolean doSomething()
>         throws Exception
>     {
>         if (_shared.value() < 10)
>         {
>             _shared.echo();
>             Continuation.suspend();
>         }
>         return (_shared.value() < 10);
>     }
> Doing this, fails with a ClassCastException, since when it hits the Method.invoke, it is potentially popping out the AnotherLoader class and does not have the Method class pushed.
