Injector#getBinding does not handle primitives the same way as Injector#getInstance

[GoogleCodeExporter]

Guice seems treat primitives and their capital-letter counterparts
inconsistently.

  public void testInjectorHandlesPrimitivesConsistently() {
    Injector inj = Guice.createInjector(new AbstractModule() {
      protected void configure() {
        bind(int.class).toInstance(1984);
      }
    });
    assertEquals(1984, (int)inj.getInstance(int.class)); // pass
    assertEquals(1984, (int)inj.getInstance(Integer.class)); // pass
    assertEquals(1984, (int)inj.getInstance(Key.get(int.class))); //pass
    assertEquals(1984, (int)inj.getInstance(Key.get(Integer.class))); //pass
    assertNotNull(inj.getBinding (Key.get(int.class)));  //pass
    assertNotNull(inj.getBinding(Key.get(Integer.class)));  //fail
  }

Shouldn't the injector return the same binding for both Key.get(int.class)
and Key.get(Integer.class)?

I'm going to fix this for 2.0:
