StackOverflowError is swallowed

The following code should have thrown StackOverflowError:

        final PublishSubject<Integer> a = PublishSubject.create();
        final PublishSubject<Integer> b = PublishSubject.create();
        a.subscribe(new Observer<Integer>() {

            @Override
            public void onCompleted() {

            }

            @Override
            public void onError(Throwable e) {
                e.printStackTrace();
            }

            @Override
            public void onNext(Integer args) {
                System.out.println(args);
            }
        });
        b.subscribe(new Observer<Integer>() {

            @Override
            public void onCompleted() {

            }

            @Override
            public void onError(Throwable e) {
                e.printStackTrace();
            }

            @Override
            public void onNext(Integer args) {
                System.out.println(args);
            }
        });
        a.subscribe(new Observer<Integer>() {

            @Override
            public void onCompleted() {

            }

            @Override
            public void onError(Throwable e) {
                e.printStackTrace();
            }

            @Override
            public void onNext(Integer args) {
                b.onNext(args + 1);
            }
        });
        b.subscribe(new Observer<Integer>() {

            @Override
            public void onCompleted() {

            }

            @Override
            public void onError(Throwable e) {
                e.printStackTrace();
            }

            @Override
            public void onNext(Integer args) {
                a.onNext(args + 1);
            }
        });
        a.onNext(1);

However, StackOverflowError is swallowed. The problem is the following line in SafeObserver: https://github.com/Netflix/RxJava/blob/0b1b6e7a91d89ad63263b80747f0bd4683fe4ba2/rxjava-core/src/main/java/rx/operators/SafeObserver.java#L117

            RxJavaPlugins.getInstance().getErrorHandler().handleError(e);

When StackOverflowError is thrown, there is few stack space. However, this line will generate too big stack frame and cause the thread crash. If I comment out this line, I can observe StackOverflowError.

Sorry, my point is that users may not be expecting to be handed such exception, and may swallow them themselves, by for example just logging them. The correct behaviour, IMHO, would be to let them bring down the JVM asap.
