Ошибка OutOfMemory в Xoom, когда другие устройства с таким же размером кучи не выдают OOM

Question

У меня странная проблема.

Я создал приложение, которое отлично работает на Samsung Galaxy S2 (размер кучи 48 МБ), но когда я тестирую его на Motorola Xoom (размер кучи также 48 МБ), оно выходит с ошибкой OutOfMemory.

Это особенно странно, поскольку из того, что я могу сказать, я на самом деле загружаю только около 20 МБ данных в кучу.

Сбой происходит в одном и том же месте каждый раз, когда я загружаю файл словаря в вектор (приложение представляет собой игру в слова, а загружаемый файл словаря занимает около 2 МБ и находится в папке ресурсов). Словарь делает это примерно так же, как слова, начинающиеся с R, а затем отбрасывают призрак.

Samsung работает под управлением Android 2.2, а Xoom работает под управлением 4.0.3

Вот код, который загружает словарь:

public class Dictionary {
    Vector words = new Vector();

    public Dictionary() {
    }

    public void loadWords(String dFile) {
        try {
            InputStream is = AndroidFileIO.assets.open(dFile);
            BufferedReader f = new BufferedReader(new InputStreamReader(is), 8192);
            String word = null;
            if (is != null) {
                while ((word = f.readLine()) != null) {
                    words.addElement(word.toUpperCase());
                }
            }
            is.close();
            f = null;
        } catch (Exception e) {
            System.err.println("Unable to read from " + dFile);
            // continue with empty dictionary
        }
    }

... и вот вывод LogCat:
