New exception in java/awt/datatransfer/ConstructFlavoredObjectTest/ConstructFlavoredObjectTest.java on Unity

Running this test java/awt/datatransfer/ConstructFlavoredObjectTest/ConstructFlavoredObjectTest.java on Ubuntu 16.04 I'm getting this new exception:

java.awt.datatransfer.UnsupportedFlavorException: text/plain
at sun.awt.datatransfer.SunClipboard.getData(java.desktop@9-ea/SunClipboard.java:215)
at ConstructFlavoredObjectTest.main(ConstructFlavoredObjectTest.java:57)

There used to be an InternalError as in JDK-8133719 -- and I still see it on Ubuntu 14.04 with Xfce -- but that UnsupportedFlavor may be something new. Please investigate.
