Fixed version (ground truth):

  final DictionaryCollection dictionaryCollection=DictionaryFactory.createMainDictionaryFromManager(this,locale,true);
  final String localeStr=locale.toString();
  Dictionary userDictionary=mUserDictionaries.get(localeStr);
  if (null == userDictionary) {
    if (LatinIME.USE_BINARY_USER_DICTIONARY) {
      userDictionary=new SynchronouslyLoadedUserBinaryDictionary(this,localeStr,true);
    }
 else {
      userDictionary=new SynchronouslyLoadedUserDictionary(this,localeStr,true);
    }
    mUserDictionaries.put(localeStr,userDictionary);
  }
  dictionaryCollection.addDictionary(userDictionary);
  Dictionary whitelistDictionary=mWhitelistDictionaries.get(localeStr);
  if (null == whitelistDictionary) {
    whitelistDictionary=new WhitelistDictionary(this,locale);
    mWhitelistDictionaries.put(localeStr,whitelistDictionary);

  dictionaryCollection.addDictionary(whitelistDictionary);
synchronized (mUseContactsLock) {
    if (mUseContactsDictionary) {
