Current status is as follows: * invocation of Eclipse for scientific computing 2020-03: crashes as before * invocation of Eclipse for scientific computing 2020-06: works!!! Didn't test thoroughly, but it shows the "Workspace" dialog and then the Eclipse main window, so if there is still anything wrong it is probably a different bug. People might still try the old versions, therefore a comment in the release notes would probably be helpful. So it's still a mystery where the reason for this incompatibility lies, but it's probably a lot of effort to find out. I don't know what happened behind the scenes, maybe it was a big effort to get the current version to run, so in any case: many thanks for all the work!
