Hi

Personally I am hoping for a solution from upstream here;  at best we
can hope to provide some fragile scripts that on a best effort basis
attempts to repair the bundles files.
  It would be a much better solution if upstream anticipated this kind
of setup and these possible mismatches.  Especially since we are much
less likely to be able to create a solid solution to assist in a 3.5 ->
3.6 migration (or similar).

I have a feeling eclipse does not support this kind of thing.
~/.eclipse/ is filled with paths and user dependent stuff.  An example:

  grep -r $USER  ~/.eclipse/

That command will fill your screen with things that are dependent on
your username alone.  If you check for "workspace" in ~/.eclipse/ it
also comes up with a couple of binary files that matches (at least in my
case).
  I would definitely not be surprised if some of this is also
architecture dependent.  Actually, if you search for "x86" (at least on
an i386) you will probably see something like[1].  So I am actually
rather confident that it is definitely architecture dependent.

On a related note, I noticed eclipse apparently dumped a lot of class
files in my ~/.eclipse, which I am trying to investigate why has happened.


You are very welcome to help us locate files that contains actual user
settings; it could very well help us inform users how (or possibly even
partly automate) to migrate preferences from 3.5 to 3.6 when we get 3.6
ready.  Though these preferences are likely to be "plugin" dependent.
