[8] Review Request: JDK-8027152 Regression: test closed/java/awt/Serialize/NullSerializationTest/NullSerializationTest.html fails since JDK 8 b112

[Petr Pchelko]

Hello, AWT Team.

Please review the fix for the issue:
https://bugs.openjdk.java.net/browse/JDK-8027152
The fix is available at:
http://cr.openjdk.java.net/~pchelko/8027152/webrev.00/

The problem:
After the fix for JDK-7081594 the ownedWindowList is used in setAlwaysOnTop. 
However the field is transient, so we get an NPE

The solution:
Move the ownedWindowList field initialization after the deserialization earlier 
that setAlwaysOnTop call.

With best regards. Petr.
