Exception in ShortestPathConnectionRouter [message #170001]

I'm trying to replace the connection router (fan+shortestpath as in ediagram
example) on-the fly with a new one and I get the following exception when
the old router is being removed.

java.lang.NullPointerException
at
org.eclipse.draw2d.ShortestPathConnectionRouter.remove(Short estPathConnectionRouter.java:169)
at org.eclipse.draw2d.AutomaticRouter.remove(AutomaticRouter.ja va:135)
at
org.eclipse.draw2d.PolylineConnection.setConnectionRouter(Po lylineConnection.java:198)
at
org.eclipse.draw2d.ConnectionLayer.setConnectionRouter(Conne ctionLayer.java:80)
....

My diagram has supernodes which one can go into so that they become contents
of the root edit part. Everything works fine except the fan+sp routers still
route the contents of the inner node taking into account information about
figures of the outer diagram. So I want to refresh the router constraints
somehow.

Sounds like a connection is being removed which the router was not aware of
for some reason. Is that possible?
