Buggy source:
private static void initializeSyncedRealm(Realm realm){
  boolean commitChanges=false;
  try {
    realm.beginTransaction();
    long currentVersion=realm.getVersion();

    final ArrayList<RealmObjectSchema> realmObjectSchemas=new ArrayList<>();
    final RealmSchema realmSchemaCache=new RealmSchema();
    for (    Class<? extends RealmModel> modelClass : modelClasses) {

      realmObjectSchemas.add(realmObjectSchema);
    }

    final RealmSchema realmSchemaCache=new RealmSchema();
    for (    Class<? extends RealmModel> modelClass : modelClasses) {
      RealmObjectSchema realmObjectSchema=mediator.createRealmObjectSchema(modelClass,realmSchemaCache);
      realmObjectSchemas.add(realmObjectSchema);
    }
