This fails on AS5 trunk, with a different exception (NPE):

The populateInvocation method is setting a null beanContext:

protected StatefulContainerInvocation populateInvocation(StatefulContainerInvocation invocation)
  |    {
  |       invocation.setBeanContext(beanContext);
  |       return invocation;
  |    }
  | 
When is the beanContext expected to be created?
