ActivityNotFoundException after refactor? watch for the missing dot! [update fixed in ADK r11]

Upodate: this is now fixed in ADT r11. Kudos to ADT team.
After refactoring Activity name from MyContactDetailsPage to ContactDetailsPage I spend a age trying to figure out why I suddenly started getting ActivityNotFoundExceptions.
Manifest before:
<activity android:name=”.contacts.MyContactDetailsPage”
android:label=”@string/app_name”
android:configChanges=”locale” />
Manifest after:
<activity android:name=”contacts.ContactDetailsPage”
android:label=”@string/app_name”
android:configChanges=”locale” />
Looks the same right? or at least the activity name has renamed, yay, but however Eclispe refactor has missed the dot prefix, so Android couldn’t find the activity, hence the exception. This drove me crazy for a good half an hour, I didn’t notice the missing dot. I guess its a good reason to use fully qualified package names when defining activities.+
