is usage of BaseEjbBean.iface safe?
If we have 1 EJB bean class, we only have 1 ENTERPRISE managed bean
and one BaseEjbBean.iface.
But if this EJB has two or more local interfaces, it can be injected
as under multiple interfaces. It seems like the interface should only
be passsed around on the stack not actually associated with the
enterprise bean itself.
Does this sound right?

Although now I'm not sure if we can properly know the injected iface
when it's time to get the instance, since we are funneled through the
Contextual.getInstance() interface.
But stashing away the injected iface in the BaseEjbBean in between
proxy creation and obtaining the instance does not seem threadsafe.

My concern is that at runtime, each time we perform injection various
threads are poking around at BaseEjbBean.iface when really all they
need to is use the iface on the stack to create their
proxies/instances. This is because there is not actually one iface
per BaseEjbBean (EJB class), just one per injection point.

Not mean that current logic is wrong.
Bean API types are local interfaces of the EJB bean . We check all injection
fields at deployment time for validation. If there is no validation error, using
of EJB local interfaces are correct.
What is the problem that you think about?

Good catch Eric!
Actually we save all of local interfaces in EJB bean and bean is requested with
one of those interfaces we supply proxy instance.
