It's great that the Opal widgets are now available as part of Eclipse Nebula,
as of the Nebula 2.0.0 release, but we've hit a snag when trying to move to
Previously, we used the Opal widgets from https://github.com/lcaron/opal. The
last release, 1.0.9, had a dependency on org.eclipse.swt with a minimum version
However, the Opal widgets from Nebula, specifically
org.eclipse.nebula.widgets.opal.commons, depends on org.eclipse.swt with a
minimum version of 3.106.0.
We are (still) using a target platform based on Eclipse Mars, which uses
org.eclipse.swt version 3.104.2.v20160212-1350.
That means we can't switch to the Nebula-packaged version of the widgets.

My guess (which could be wrong) is that when they were moved to Nebula, that
was done using an Eclipse Oxygen IDE, and someone that got inserted as the
minimum version required, but it's not actually needed.
Is it possible to reduce or remove the minimum SWT version that the Opal
