r1808930 forbidden-api checks and imports

[Allison, Timothy B.]

Dominik,
Thank you for fixing my new PrintStreams so that the forbidden-api checks would 
pass...head in hands.  I noticed that imports were shortened to wildcards.  
Should I flip back to listing all?
Thank you, again!

      Best,

                  Tim
