Describe the bug
ANNIS 4 fails to start on Kubuntu 20.10. It appears to be caused by the java.awt.Desktop.browse method which doesn't seem to be well supported in the KDE.

To Reproduce

Steps to reproduce the behavior:
java -jar annis-4.0.0-beta.6-desktop.jar

Expected behavior

The url can be open by the user, but the bug results in program crash.

Screenshots

Thanks for the bug report, there is some code to handle exceptions and prompt the user to manually open the site in

ANNIS/src/main/java/org/corpus_tools/annis/gui/ServiceStarterDesktop.java

Line 231 in a1c04cc

} catch (IOException | URISyntaxException ex) {
but it seems the UnsupportedOperationException was missed. I will also check if there is a workaround for KDE systems to actually automatically open the browser.
