I then ran the application, and clicked the "Help" button on the main application window, and got the same error message as before (no change). Just to make sure, I rebooted, then ran the test again. I got the same error message as before (no change). - Aere -- Sincerely, Aere -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-8 in Ubuntu. https://bugs.launchpad.net/bugs/1574879 Title: Java Desktop.browse not supported on Kubuntu 16.04 Status in openjdk-8 package in Ubuntu: New Bug description: The Desktop.browse functionality of Java is not supported on the Kubuntu 16.04 level of the KDE desktop. It was supported in earlier levels. With this support no longer available, a Java application can no longer activate the system's browser to display the already-installed HTML help files for the application, making the context-sensitive help functionality useless. Here is the Java code snippet where the code attempts to activate the online help: if (Desktop.isDesktopSupported()) { Desktop desktop = Desktop.getDesktop() ; if (desktop.isSupported(Desktop.Action.BROWSE)) { try { desktop.browse(new URI(url)) ; } catch (Exception e) { String error = "Problem creating URI to access documentation:\n" + e.getMessage() ; reportError(error, true) ; } } else reportError("Desktop.browse not supported on this system.", true) ; } When this code is executed, the "Desktop.browse not supported on this system." error message is displayed, rather than activating the user's Internet browser to display the HTML help file already installed in the user's file-system. In prior releases of Kubuntu, this has always worked. I expected it to work on 16.04 (as it does on the other 'flavors' of Ubuntu 16.04), but it is not supported in the KDE desktop of Kubuntu 16.04 I am using Kubuntu 16.04. In prior releases of Kubuntu, the online help information was displayed using the system's Internet browser, which was what I expected to happen. In this release, I instead got the "Desktop.browse not supported on this system." error message, and the Internet browser was not activated to display the already-installed (via Debian package) help information.
