<AWT Dev> [9] Review Request for 8081306: remove imports of the internal API from some regression tests

[Yuri Nesterenko]

Colleagues,

please review this test fix to
https://bugs.openjdk.java.net/browse/JDK-8081306

Webrev
http://cr.openjdk.java.net/~yan/8081306/webrev.00
closed tests moved to open, diffs:
http://cr.openjdk.java.net/~yan/8081306/webrev.diff.00

 From the tests removed some unused import instructions.
Without modular system in place, this is a meaningless
change, however with modular discipline they
just don't compile.

Thank you!
