Hi,
I tried to use BorderRectilinerRouter for a connection figure in Graphiti 0.9.2.

This router was explicitly set instead of FreeFormConnectionRouter of Graphiti. The creation of connection works fine, however when I shift the connection by holding bendpoints, I get following exception and the refresh of diagram gets hanged. On my initial analysis, I found the newLine was infact 0 in size, which on calculation of newLine.size()-1 resulted in -1, in RectilinearRouter.routeLine at Point lastEndAnchor = newLine.removePoint(newLine.size() - 1);

Also it was found that below method was in fact returning pointlist empty:

ObliqueRouter.calculateBendPoints(Connection conn)

java.lang.IndexOutOfBoundsException: Index: -1, Size: 0
at org.eclipse.draw2d.geometry.PointList.removePoint(PointList.java:334)

at org.eclipse.gmf.runtime.draw2d.ui.internal.routers.ObliqueRouter.route(ObliqueRouter.java:195)

Please suggest how to resolve this issue.

Thanks,
Kunal
