Request for approval: 8043850 REGRESSION: java/awt/dnd/DragSourceListenerSerializationTest/DragSourceListenerSerializationTest.html fails with NPE since 8u20 b07 on Linux

[Petr Pchelko]

Hello,

This is a request for approval to back port a fix from JDK9 to JDK8u-dev.

The bug report is not public at a moment, but the problem is that serialized DnD classes cannot be properly deserialized back.
The JDK9 fix: http://hg.openjdk.java.net/jdk9/client/jdk/rev/b35c7f58d9a1
9 changeset applies cleanly.

Thank you.
With best regards. Petr.
