onException called with null Throwable in OnAlbumsListener

[ravimittal99]

I use this login listener to login. After login, it's coming to onException of "onAlbumsListener". When i try to inspect "throwable" in onException to know what the error is, it's null. I use simple.facebook-2.2

private OnLoginListener mOnLoginListener = new OnLoginListener() {

    @Override
    public void onException(Throwable throwable) {

    }

    @Override
    public void onFail(String reason) {

    }

    @Override
    public void onLogin() {

        mSimpleFacebook.getAlbums(onAlbumsListener);

    }

    @Override
    public void onNotAcceptingPermissions(Type arg0) {

    }

    @Override
    public void onThinking() {

    }

};

protected OnAlbumsListener onAlbumsListener = new OnAlbumsListener() {

    @Override
    public void onException(Throwable throwable) {
    //throwable is null here
        super.onException(throwable);
    }

    @Override
    public void onFail(String reason) {
        super.onFail(reason);
    }

    @Override
    public void onComplete(List<Album> albums) {

        super.onComplete(albums);
    }

};
