I cannot duplicate this.  I added the ECF update site [1] and it
defaulted to ~/.eclipse/<something or other>.

I'm still quite confused.

Why are you trying to update files owned by system-installed RPMs?  This
will break verification of these RPMs.  It also won't work.  If you want
to use upstream releases, just download a zip and put it in your home
directory somewhere.

This sounds like you don't like the Eclipse Update Manager.  You're not
alone in this :)

These all seem like upstream project (BIRT, whatever) issues.  Or
network issues.  If you can track down specific Fedora Eclipse issues,
it would be great if you could file bugs at bugzilla.redhat.com.

That sounds like a VM crash.

It looks like you have a lot of files that have changed on disk since
their RPM installation.  I don't know what to say about that except that
it *could* be affecting your installation.  As per usual with eclipse
stuff, try with different VMs, with the -clean startup option, with a
new workspace with ~/.eclipse out of the way without any 3rd party
plugins, etc., etc.  If you can reliably reproduce issues, file bugs in
Red Hat bugzilla and people can take a look.
