Remove SlideListener inside a listener will throw ConcurrentModificationException

Created by: blueberry6401

I have something like

new SlidingUpPanelLayout.SimplePanelSlideListener() {
            @Override
            public void onPanelStateChanged(...) {
                mSlidingLayout.removePanelSlideListener(this);
            }
}

This will throw ConcurrentModificationException.
