Hi,
Bug : https://bugs.openjdk.java.net/browse/JDK-8134612 Issue : In this test, exportToClipboard() does not export anything to the clipboard due to incorrect text passed to TransferHandler. Obviously, when we do clipboard.getData() - it throws UnsupportedFlavorException. This is the root cause. Also, when text is imported, the text String cannot be assigned to MyStringReader class. Fix : The test is corrected to use custom dataflavor containing String to export and import from clipboard. Also, the test is enhanced to test a custom dataflavor of Color. I have referred to : https://docs.oracle.com/javase/tutorial/uiswing/dnd/dataflavor.html It passes consistently on Windows, Linux and Mac. Webrev : http://cr.openjdk.java.net/~aghaisas/8134612/webrev.00/ Request you to review. Regards, Ajit
