I've nearly got a first spike of the JSR 250 support for @Resource
going in GuiceyFruit using the current trunk of Guice. But I just
banged my head when attempting, inside
InjectionListener.afterInjection() to get the Encounter.getProvider()
- to try look up a dependent object that I need.
For example for JSR 250 the InjectionListener needs to get a JNDI
Context object - which I was hoping to use Guice to dependency inject.
When I saw the getProvider() methods on Encounter I figured this was
the way of asking for a provider from inside an InjectionListener?
Maybe I'm using the wrong API or maybe there's a small bug? Or maybe
its just not possible to inject an InjectionListener? (The latter
could be true due to ordering issues).
FWIW here's the stack trace if it helps... Anyone got any ideas?
.

If its any help the source of the code using the InjectionListener /
Encounter is here...
http://code.google.com/p/guiceyfruit/source/browse/trunk/guiceyfruit-core/src/main/java/org/guiceyfruit/support/AbstractGuiceyFruitModule.java
e.g. this is the line causing the issue:
http://code.google.com/p/guiceyfruit/source/browse/trunk/guiceyfruit-core/src/main/java/org/guiceyfruit/support/AbstractGuiceyFruitModule.java#63
when we attempt to inject an AnnotationMemberProvider instance so we
can inject a member
