[quickfix] Inconsistent hierarchy not generating suggestions

[kriegfrj]

One of the reasons I created the quick fix processor was to help in figuring out what my missing transitive dependencies were, as this was a laborious process.

It used to work well, but I have noticed recently that it doesn't seem to be working. I suspect there must have been a change in JDT that we haven't caught up with which is causing it to fail now.

Testing and debugging this could be painful as it might require upgrading the version of Eclipse we have in the dev workspace. We do have some test cases that could help (though they are disabled in CI because of persistent flakiness), and perhaps (on a related note) we could even consider having two bndrun files for these tests (one for the baseline version of Eclipse and one for the latest version).
