Description Pierre-Charles David CLA 2015-09-11 10:30:21 EDT 
+++ This bug was initially created as a clone of Bug #430086 +++

When using EcoreTools 2 I sometime have a few ClassCastException being trown.

I don't have yet a perfectly reproductible scenario but it happens when I am moving edges (which have a rectilinear routing) to layout them.

java.lang.ClassCastException: org.eclipse.gmf.runtime.diagram.ui.internal.figures.ResizableLabelLocator cannot be cast to org.eclipse.draw2d.geometry.Rectangle
