It looks like it is only crashing when using an object property through the linking object. It is this Java test:

                case OBJECT:
                    assertEquals(2, realm.where(AllJavaTypesUnsupportedTypes.class).isNotEmpty(AllJavaTypesUnsupportedTypes.FIELD_LO_OBJECT   "."   AllJavaTypesUnsupportedTypes.FIELD_OBJECT).count());
                    break;

AllJavaTypesUnsupportedTypes.FIELD_LO_OBJECT is a LinkingObjects collection and AllJavaTypesUnsupportedTypes.FIELD_OBJECT is an object reference.

It is this query that is crashing: @links.AllJavaTypesUnsupportedTypes.fieldObject.fieldObject.@count != 0

On this dataset. fieldId is a integer primary key field.

        AllJavaTypesUnsupportedTypes obj1 = new AllJavaTypesUnsupportedTypes();
        obj1.setFieldId(1);
        obj1.setFieldObject(obj1);
        realm.copyToRealm(obj1);

        AllJavaTypesUnsupportedTypes obj2 = new AllJavaTypesUnsupportedTypes();
        obj2.setFieldId(2);
        obj2.setFieldObject(obj2);
        realm.copyToRealmOrUpdate(obj2);

        AllJavaTypesUnsupportedTypes obj3 = new AllJavaTypesUnsupportedTypes();
        obj3.setFieldId(3);
        obj3.setFieldObject(null);
        realm.copyToRealm(obj3);

All 3 objects are required to trigger the crash, creating any 2 of them doesn't crash.
