I recently upgraded our eclipse rcp app which uses gef zest sdk (org.eclipse.gef.zest.sdk.feature) from version 5.0.2.201901221055
to 5.1.2.202012080300. The graph part of our application no longer works.

The graph is drawn correctly, but as soon as I click on a node and try to move it a large number of exceptions are generated. The same problem occurred for me when I tried to run the JFaceFontsExample (from org.eclipse.gef.zest.examples.jface).

The first exception generated is this:
java.lang.IllegalStateException: java.lang.IllegalArgumentException: Not enough bend points supplied!

i caught this problem as same as you.my solution is to lower your gef version,and this problem resovled.you can use a eclipse package without installing gef,then install gef 5.0.xx version instead of newer version like 5.2.xx version.
