Thanks for the suggestion Jan.
I now check if the logger is null in the matcher which gets me passed that
issue.
Also, I think I solved my second issue with the listener itself throwing
NPEs from the encounter. I don't think I was using it right before.
Basically, the fix was something like this:
1. When I register a new injection listener with the encounter, I get
the providers from the encounter as fields in the listener. (Before I was
trying to get the objects from the providers as fields which resulted in
the NPEs.)
2. Then in the afterInjection method, I use the providers to actually
get() the instances.
i.e. In my InjectionListener class:
// Fetch the log object provider from guice
private final Provider<Logger> logProvider =
encounter.getProvider(Logger.class);
@Override
public void afterInjection(I injectee)
{
Logger log = logProvider.get();
...
Hope that helps anyone else that runs into this.
