[Java] Something wrong with se/de int <-> Integer fields when compatible_mode

[urlyy]

I have noticed #2641, but I'm a bit confused about FieldConverter, Does the user need to use it explicitly for the conversion?

Minimal reproduce step

static class Demo1 {
    int f1;
    int f2;
    Integer f3;
    Integer f4;
    Integer f5;
    Integer f6;
}
static class Demo2 {
    int f1;
    Integer f2;
    Integer f3;
    int f4;
    int f5;
    Integer f6;
}

@Test
public void testInteger2() {
    Fory fory1 = Fory.builder().withLanguage(Language.XLANG).withCompatibleMode(CompatibleMode.COMPATIBLE).build();
    fory1.register(Demo1.class, 101);
    Fory fory2 = Fory.builder().withLanguage(Language.XLANG).withCompatibleMode(CompatibleMode.COMPATIBLE).build();
    fory2.register(Demo2.class, 101);

    Demo1 demo1 = new Demo1();
    demo1.f1 = 1;
    demo1.f2 = 2;
    demo1.f3 = 3;
    demo1.f4 = 4;
    demo1.f5 = null;
    demo1.f6 = null;

    byte[] serialize = fory1.serialize(demo1);

    Demo2 demo2 = (Demo2) fory2.deserialize(serialize);
    Assert.assertEquals(demo2.f1, 1);
    Assert.assertEquals(demo2.f2, 2);
    Assert.assertEquals(demo2.f3, 3);
    Assert.assertEquals(demo2.f4, 4);
    Assert.assertEquals(demo2.f5, 0);
    Assert.assertNull(demo2.f6);
}

What did you expect to see?

pass unit test

What did you see instead?

panic at Assert.assertEquals(demo2.f2, 2);

java.lang.AssertionError:
Expected :2
Actual   :-448
