In rare cases while RoundedBendpoints are activated some connections aren't drawn, instead only some weird artifacts show up. After some debugging i found out that it happens if the length of a segment between two bendpoints is exactly twice the roundedBendpointradius.
Changing line 1974 of the org.eclipse.gmf.runtime.draw2d.ui.geometry.PointListUtilities class from
if (r > distance / 2) {
to
if (r >= distance / 2) {
does fix the problem for me.

Reproducible: Always

Steps to Reproduce:
1.activate roundedbendpoints
2.have a connection with a segment twice the length of the rounded bendpoint radius
