Or rather, it is On My Machine (tm): The mobile SDK packages are found
(and autocomplete works for packages), but no classes. Libraries are
visible in the project-tree, and can browse through them just fine.
Tried re-creating the project, the mobile sdk - no joy.
If I re-open the project in 7.0 (#7930) all is fine.
Is there some sort of 'know issues' document? Couldn't find it.
