Let me guess... r u invoking your code from *within* your custom MyLocationOverlay code ?
I had the same Java exception as you until I moved my overlay updating code OUT of my custom MyLocationOverlay class. It seems that MyLocationOverlay also maintains a handle on the overlays list, so that appeared(at least for me,) to be the source of the ConcurrentModificationException.
