<AWT Dev> [9] Review Request: 8043393 NullPointerException and no event received when clipboard data flavor changes

[Sergey Bylokhov]

Hello.
Please review a fix for jdk 9.
The NPE occurs, because we call getDefaultFlavorMap() on the Toolkit 
thread 
(formatArrayAsDataFlavorSet->getDefaultFlavorTable->SystemFlavorMap.getDefaultFlavorMap()).
But after the fix of JDK-8030679 a DefaultFlavorMap is stored per 
AppContext, so we cannot use it on the TK thread. As a fix I suggest to 
store raw formats instead of Set<DataFlavor>.
