Jonathan S Fisher commented on OWB-714:
---------------------------------------
Experiencing the same problem. I'm fairly certain Instance<> was designed to
work transparently. Take a look:
An InjectionPoint object provides metadata information about an injection
point. An instance of InjectionPoint may represent one of the following types:
* an injected field
* a parameter of a bean constructor
* an initializer method
* a producer method
* a disposer method
* an observer method
I would propose one of the purposes of Instance<> class was to allow for
non-serializable objects to be proxied and injected into serializable beans.
While the spec isn't specific, I'm having a hard time imaging a use case where
a developer would want to get ahold of the Instance proxy instead of the
proxied object. I would argue the Instance<> class was designed to be
transparent.

> EmptyStackException when accessing an Instance that is created by a producer
> method that has an InjectionPoint as parameter.
> The following code leads to the exception:
> public class MyProducingBean {
> @Produces
> public MyProducedBean produceBean(InjectionPoint ip) {
> ...
> }
> }
> public class MyUsingBean {
> @Inject
> private Instance<MyProducedBean> beanInstance;
> public void someMethod() {
> beanInstance.get(); // throws EmptyStackException
> }
> }
