In the following code:

        Integer myValue = 100;
        Assert.assertEquals((Integer) 50, myValue);

I have a warning "Unnecessary cast to Integer". After using hint I got the following code:

        Integer myValue = 100;
        Assert.assertEquals(50, myValue);

which throws the compile error:

error: reference to assertEquals is ambiguous
        Assert.assertEquals(50, myValue);
  both method assertEquals(Object,Object) in Assert and method assertEquals(long,long) in Assert match
