possibly due to line 128 restore_finalisation.php

We're going to have to get tricky with this file. The intent is to overload the core classes, so as they're now namespaced, the overloading has to use the correct namespacing as well.

I think this is right (there are no IDE reported errors and no reported syntax errors linting the file), but I never write files using multiple namespaces, so I have no idea if this is going to do what we want it to.

I can confirm this issue.

@mbabker After adding the proposed file https://gist.github.com/mbabker/5e171b1df99f71a30290125e0292b1d9 to an update or full package (Nightly Builds) I could update via Upload&Update without any issues. AJAX error is gone.

@mbabker @brianteeman Any progress of this issue? How we have to deal with this file ?

[mbabker]

If the comment from @ReLater is any indication of success, just need a pull request updating administrator/components/com_joomlaupdate/restore_finalisation.php with the contents of the gist.
