I'm afraid to remove it, as I might not be able to reinstall it later. I would guess it's not directly part of the problem (it doesn't show up in the trace), but perhaps the long history of these two installations confused Install New Software.

Can you try logging in as a different user to see if Eclipse still exhibits the problem? This should eliminate the involvement of any custom plugins you have installed in your own ~/.eclipse area.
I'm pretty sure I know what the issue is. It's failing in the new patch created to filter out droplet entries from the dropdown. One of the update sites doesn't have a path. As a workaround, you could try going into Window -> Preferences. Under Install/Update, go to Available Software Sites, and remove any update sites that aren't valid URLs, or local file paths.
A non-URL, non-file-path is exactly what I wanted to install from (a local zip archive). Unzipping it somewhere and installing from that worked.
If you're able to reproduce the issue, could you try updating to https://koji.fedoraproject.org/koji/buildinfo?buildID=839511 and see if it still occurs ? You would only need to download the same packages you already have on your system (eg. eclipse-pde, eclipse-equinox-osgi, eclipse-jdt, eclipse-swt, eclipse-platform).
I am able and I'll try to do it on my other machine (the desktop is happy using the plain (non-archive) repo).
Confirmed that the fix works for me.
