этот простой пример приводит к исключению
public static void main(String[] args) throws InterruptedException {
MongoClient mongoClient = MongoClients.create("mongodb://localhost");
MongoDatabase db = mongoClient.getDatabase("import");
MongoCollection<Document> gameEntityCollection = db.getCollection("gameEnitites");
gameEntityCollection.watch().subscribe(new Subscriber<ChangeStreamDocument<Document>>() {
@Override
public void onSubscribe(Subscription s) {
s.request(1);
new Thread(() -> {
try {
Thread.sleep(100);
s.cancel();
} catch (InterruptedException e) {
e.printStackTrace();
}
}).start();
}
@Override
public void onNext(ChangeStreamDocument<Document> t) {
}
@Override
public void onError(Throwable t) {
}
@Override
public void onComplete() {
}
});
Thread.sleep(10000);
}
Это исключение выглядит безвредным и регистрируется асинхронно.
