JNA — метод обратного вызова с аргументами void*

У меня есть метод C, который регистрирует метод обратного вызова с предоставленной поставщиком dll. Мне сказали, что DLL делает обратный вызов в отдельном потоке, который он создает и контролирует. Есть 3 возможных различных сообщения данных, которые могут быть получены обратным вызовом получения.

// Register user receive callback function
int PTOAPI_MODE PTOregReceivedCB(void (__stdcall *pUsrFunc3)(void* lpData,int iDataLen));

Я использовал JNAERATOR для создания кода интерфейса JAVA, который сгенерировал ниже код сегмента,

/// <i>native declaration : Ptsptoext.h:728</i>
    public interface pUsrFunc3 extends Callback {
        void invoke(Pointer lpData, int iDataLen);
    }

    /**
     * Original signature : <code>PTOregReceivedCB(pUsrFunc3)</code><br>
     * <i>native declaration : Ptsptoext.h:728</i>
     */
    @Mangling({"_Z16PTOregReceivedCBPFvPviE", "?PTOregReceivedCB@@YAXPFXPAXH@E@Z"}) 
    int PTOregReceivedCB(TofapiLibrary.pUsrFunc3 arg3);

Я запустил код в простом основном методе, чтобы убедиться, что я могу получить обратный вызов от dll, как показано ниже.

main(){
...
        success = tofLib.PTOregReceivedCB(new TofapiLibrary.pUsrFunc3() {

            @Override
            synchronized public void  invoke(Pointer lpData, int iDataLen) {
                System.out.println("PTOregRecievedCB has been called with data lenght = " + iDataLen);
            }
        });
.....
}

Когда я запускаю свой тест, он успешно регистрирует обратный вызов с dll. Но позже, когда dll пытается вызвать метод обратного вызова, jvm дает сбой еще до того, как достигает метода обратного вызова в JAVA. Отчет об исключении показывает, что «Инструкция по адресу «0x0b543a46» ссылается на память по адресу «0x0651acc». Память не может быть «прочитана»». Я подозреваю, что указатель в обратном вызове терпит неудачу. Вы видите что-то не так с моим кодом? Есть ли что-то, что мне нужно для объекта Pointer в обратном вызове? Я не могу прочитать приведенный ниже отчет об исключении, который был создан при сбое JVM. Ваша помощь будет принята с благодарностью.

Вам нужно сохранить сильную ссылку на объект обратного вызова java, иначе он будет собирать мусор, и JVM выйдет из строя, когда собственный код попытается вызвать его. См. https://jna.dev.java.net/javadoc/com/sun/jna/Callback.html

например Это сохраняет ссылку на обратный вызов в статической переменной класса.

static final TofapiLibrary.pUsrFunc3 myCallback = new TofapiLibrary.pUsrFunc3() {

        @Override
        synchronized public void  invoke(Pointer lpData, int iDataLen) {
            System.out.println("PTOregRecievedCB has been called with data lenght = " + iDataLen);
        }
};

Позже в вашем основном коде просто выполните:

    tofLib.PTOregReceivedCB(myCallback);
