1) There is an issue in the ScrollBar behaviour in Aqua L&F.
- Move mouse to the ScrollBar track
- Press left mouse button (the thumb is moved under the mouse cursor)
- Drag the mouse to the track

The thumb is not dragged in this case because this action is treated as movinf the mouse cursor from one part of the track to another.

The solution is unsetting the stillInTrack flag when the thumb has been moved under the cursor by the scroll timer.

2) The test hangs because it does not wake up in case an adjusment event is not received. The test need to be rewritten to fail in this case.

The issue with the ScrollBar in Aqua L&F is fixed in the macosx repository
http://hg.openjdk.java.net/macosx-port/macosx-port/jdk/rev/ca571a48818c

Now the test fails on Windows because it expects to use longer delays between mouse moving and mouse release actions. 
This is covered in the issue 7120869 javax/swing/JScrollBar/4708809/bug4708809.java fails on Windows.
