<AWT Dev> Review Request: JDK-8028230 Behavior of SystemFlavorMap.getNativesForFlavor differ from that in Java 7

[Petr Pchelko]

Hello, AWT Team.

Please review the fix for the issue:
https://bugs.openjdk.java.net/browse/JDK-8028230
The fix is available at:
http://cr.openjdk.java.net/~pchelko/8028230/webrev/

The problem: when initializing the flavor map, for text flavors we do the following: for a mime-type we find all DataFlavors and find add natives for that flavors and store them in a list. However, the list  could contain duplicated natives, so we should first accumulate them in a Set and then convert to a list.

The fix verified with all reg tests from dnd, clipboard and datatransfer and SQE tests for datatransfer and Clipboard. Now new failures, 2 SQE tests fixed.

Thank you.
With best regards. Petr.
