Callback C++ function from Java: object references mismatch

[morte]

I have QAndroidJniObject (CppClass::jniObject) with MyJavaClass.java class instance. MyJavaClass calls native callback anSignalFromJava()

static native void anSignalFromJava();

Callback function on C++ side:

extern "C" {
JNIEXPORT void JNICALL Java_org_example_MyJavaClass_anSignalFromJava(JNIEnv* env, jobject object) {

  qDebug() << "callback object=" << object << "CppClass::jniObject.object()=" << CppClass::jniObject.object(); 
//output: callback object=0xbea037fc CppClass::jniObject.object()=0x572

  Q_ASSERT(object == CppClass::jniObject.object()); //fail
}
}

References to same Java object provided by QAndroidJniObject and object parameter of callback function differs, but they should be same
