Changing package hierarchy / levels doesn't work

[9ert]

When you try to change the package hierarchy / level of a class, it looks like the imports in other classes are not updated / corrected.

If you for example want to flatten a package hierarchy by removing in the following case the 'module' path:

module.printer -> printer

The printer.class seems to be updated properly ('package module' will be removed etc), the imports in other classes will still refer to the old package path though:

import module.printer;

Introducing a new package level has the same effect.

P.s. great work though so far (unfortunately didn't manage to fix it myself)!
