In fact it's not a but - its about Eclipse internal architecture and file permissions. User who wants to install extension has to go to Eclipse Help-> Software Updates -> Manage configuration and add extension location placed in his userspace.
Then he can install plugins in there.
So, this is not a bug for me but Ubuntu could provide some extension to Eclipse that could install userspace extensions somewhere in ~/.eclipse by default.
