[7u40] Request for phase 2 approval for CR 8019628 - [macosx] closed/java/awt/Modal/BlockedMouseInputTest/BlockedMouseInputTest.html failed since 7u40b30 on MacOS

[Alexander Scherbatiy]

   Hello,

This is a request for phase 2 approval to push the fix for 8019628 into 
the 7u40 repository.
This is a a regression from the last merge in the JDK 7u40 so only fix 
for the JDK 7u-dev is prepared.

Bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8019628
Webrev:  http://cr.openjdk.java.net/~alexsch/8019628/webrev.00
Review thread: 
http://mail.openjdk.java.net/pipermail/awt-dev/2013-July/005083.html
Reviewers: Sergey Bylokhov, Leonid Romanov

Generated enter/exit mouse events have been changed to use the current 
mouse event id during the last merge in the JDK 7u40.
The mouse enter/exit events are now can be lost and wrong events can be 
sent for the lastMouseEventPeer.
The fix returns the explicit mouse enter/exit events declaration back as 
it was before the merge.

Thanks,
Alexandr.
