<AWT Dev> [9] Review Request: JDK-8043513 Clipboard#getContents(Object) throws IOException

[Petr Pchelko]

Hello, AWT Team.

Please review the fox for the issue:
https://bugs.openjdk.java.net/browse/JDK-8043513
The fix is available at: 
http://cr.openjdk.java.net/~pchelko/9/8043513/webrev/

The problem:
When we fetch all contents from the clipboard we catch IOException and store it for later.
In case we would then need the data which caused the exception the cached exception would be rethrown.
But the stack trace shows where the exception was created, not thrown. Wrapping it helps to 
eliminate the misunderstanding.

With best regards. Petr.
