I tried your suggestions and they work. However, I still am able to select a connection and move its endpoints to another anchor. I override getMoveShapeFeature() that returns null, but it does not apply to Connections since they are not Shapes.

moving an endpoint means reconnecting a connection. For this the reconnection feature is asked, default implementation is DefaultReconnectionFeature queried from IFeatureProvider.getReconnetionFeature.
