A DESCRIPTION OF THE REQUEST :
You should be able to get a Package object for any class.  You should also be able to specify Package objects as constants (available to annotations) through syntax like "com.mypackage.MyClass.class.package" or "com.mypackage.package".

JUSTIFICATION :
The ability to specify packages would allow annotations to specify packages.  In particular, I would like to see a feature like @VisibleTo((Class|Package)+) and @VisibleToSubPackagesOf(Package+) as ways of sharing default access classes and members with other classes and packages (without making them public or protected).  This would very neatly solve a problem that we've had since the beginning.  I've been thinking about this problem for the last 9 years or so and this is the best idea I've come up with because it is Java simple.  I hope we can fix this serious lacking simply like this...

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Ability to reference Package objects easily through the Java language and through annotations.
ACTUAL -
Feature does not exist.

CUSTOMER SUBMITTED WORKAROUND :
No easy workaround.  Package objects are not consistently available for classes and there is no way to access them directly in the language or through annotations.  The @VisibleTo*() annotations I'd like to see are not possible at all right now.
