Injection of a SLF4J Logger - only injects once

I am wanting to inject a org.slf4j.Logger into classes that need it instead of declaring it as static at the top and specifying the class name eg.

private static final Logger log = LoggerFactory.getLogger(Application.class);

To do so I have created a producer method like so

@Produces
public Logger getLogger(InjectionPoint injectionPoint)
{
    return LoggerFactory.getLogger(injectionPoint.getMember().getDeclaringClass().getName());
}

And then I inject it using @Inject but it only seems to do inject for the first class that requests it, all other classes that have a org.slf4j.Logger injection point end up with a NPE

I do use the described logic and it is working, could you provide a minimal (non) working example for your case? – Dominik Sandjaja Oct 29 '15 at 10:17
trying to create a short non working example for you and failing at the moment :( – PDStat Oct 29 '15 at 10:52

Yeah, that is why a short code sample would be nice ... Because the given code snippet looks OK, hence the problem must be elsewhere in the usage. – Dominik Sandjaja Oct 29 '15 at 10:54
You may want to provide some basic info like what does your runtime look like, container, java version, etc. – John Ament Oct 30 '15 at 01:13

Why would you want to use @Inject for loggers? – Adrian Mitev Oct 30 '15 at 22:01
