Couldn't reproduce locally. Please next time the problem is reproduced on your side, run the small program below and attach its output to this bug (or file a new one). Make sure NOT using the system clipboard from the moment of exception till running the test program. import java.awt.*; import java.awt.datatransfer.DataFlavor; public class ClipboardDump { public static void main(String[] args) { System.setProperty("java.util.Arrays.useLegacyMergeSort", "true"); DataFlavor[] dataFlavors = Toolkit.getDefaultToolkit().getSystemClipboard(). getAvailableDataFlavors(); for (DataFlavor df: dataFlavors) { System.out.println(df); } } }
