Realm save data in one thread acquire in another

I have two threads which don't work with UI thread. In one thread I receive JSON from server and save it to Realm DB : 

Realm realm = Realm.getDefaultInstance();
final RealmResults<MyClass> all = realm.where(MyClass.class).findAll();
realm.executeTransaction(new Realm.Transaction() {
            @Override
           public void execute(Realm realm) {
           all.deleteAllFromRealm();
           realm.createOrUpdateAllFromJson(MyClass.class, recommendations);
      }
 });
 realm.close();

Then, in another thread after interaction with user I need to acquire this information, but it is unavailable : 

 Realm realm = Realm.getDefaultInstance();
 RealmResults<MyClass> responseItems = realm.where(MyClass.class).findAll();
 realm.close();

So when I acquire data on the thread where I added them I can see them, on other threads they are unavailable. How can I merge information on different threads or notify instances to Update ?

Using : io.realm:realm-gradle-plugin:1.0.0

UPDATE : Information from different tables merges after application restart.

I found a workaround - even if I don't need any transaction I call .beginTransaction() before call where(clazz.class) and data is up to date.
