This exception happens when your marker was reclustered by ClusterManager. ClusterManager recreates marker on clustering. So, to avoid it you must get your marker from render of ClusterManeger:

ClusterIconRender render = (ClusterIconRender) mClusterManager.getRenderer();
Marker trueMarker = render.getMarker(clusterMarker);
if (trueMarker != null) {
    trueMarker.setIcon(...);
    ... // do whatever else your want with marker
}

In code above ClusterMarker implements ClusterItem and ClusterIconRender extends DefaultClusterRenderer.
