@Extra on primitives doesn't compile with javac

[pyricau]

Given the following code :

@EActivity
public class ExtraInjectedActivity extends Activity {

    @Extra("intExtra")
    int intExtra;

}

The interesting part of the generated code is :

public final class ExtraInjectedActivity_
    extends ExtraInjectedActivity
{
    // ...

    private void init_(Bundle savedInstanceState) {
        Bundle extras_ = this.getIntent().getExtras();
        if (extras_!= null) {
            if (extras_.containsKey("intExtra")) {
                try {
                    intExtra = cast_(extras_.get("intExtra"));
                } catch (ClassCastException e) {
                    Log.e("ExtraInjectedActivity_", "Could not cast extra to expected type, the field is left to its default value", e);
                }
            }
        }
    }

    @SuppressWarnings("unchecked")
    private<T >T cast_(Object object) {
        return ((T) object);
    }

}

It compiles well with Eclipse compiler.

It does not compile with javac compiler, giving the following error :

type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds int,java.lang.Object

The problematic line is:

intExtra = cast_(extras_.get("intExtra"));

The problem is kind of related to the one described here.

Also note that the problem disappears if we use wrappers instead of primitives :

@EActivity
public class ExtraInjectedActivity extends Activity {

    @Extra("intExtra")
    Integer intExtra;

}

We'll fix that by using traditional casting in case of primitive types
