Injecting the current App in Play 2.5.2 - scala

Question

I am using the DI to access my App in Play 2.5:
import com.google.inject.{Inject, Provider}
import play.api.mvc._
import play.api.Application
class ApplicationController #Inject()(p: Provider[Application]) extends Controller {
implicit lazy val app = p.get()
println(app.hashCode()+"") // Random line to use the injected app
}
I am getting the following error :
ProvisionException: Unable to provision, see the following errors:
1) Tried proxying play.api.Application to support a circular dependency, but circular proxies are disabled. ...
I went on the Play Migration guide : https://www.playframework.com/documentation/2.5.x/Migration25#Handling-legacy-components
and did as they say to avoid circular dependency, however I still have that error.
I've also found a variable called disableCircularProxies which I am not currently using (http://google.github.io/guice/api-docs/latest/api-diffs/changes/docdiffs_com.google.inject.html) as I am not sure how to do so and found very little info about it.
Any idea how to solve this circular dependency error ?
Here is the full stack trace :

Ultimately, I shouldn't be using this Provider[Application] but rather the configuration, environment, ... from the App.
It's just that according to the doc, I should be able to have that working.

Java Version:
#Inject
private Provider<Application> application;
private void someMethod {
...
application.get();
}
