Hello,
I need to run Knime 4.1 on Linux RHEL8 but I keep having issues to start the application despite the fact it I followed the same procedure that for KnimeAP 5.4 installed on the same machine.
I keep having the error message
Unable to init server: Could not connect: Connection refused
Knime: Cannot open display:
CompilerOracle: exclude javax/swing/text/GlyphView.getBreakSpot

I need it as a we have a large set of workflows built on KnimeAP 4.1 and we would prefer to keep opening them in the original version before we rebuild them in a modern KnimeAP version benefitting of all the improvements.
If not possible, any experience here about opening very old workflows on recent version Of Knime? Any major incompatibilities before we start migrating? We have 200+ workflows to migrate and it may wor on some but not on others and I would prefer to secure the approach before starting based on your experience…
May be it would be possible to select an intermediate version that would run on RHEL8 and still guarantee compatibility of all features present in Knime 4.1?
