To provide an embedded web browser, we've put in JxBrowser as a replacement for Lobobrowser. We have been using an evaluation license for JxBrowser. Sadly, we have not been able to obtain a proper license. We must remove JxBrowser again.
Ideally, we'd introduce a feature-rich browser, like JCEF. Switching to that is non-trivial though. This effort is tracked in SPARK-1914.
As an in-between solution, we can revert back to the old LoboBrowser implementation, which has now been made available through maven. It won't be as feature rich, but does allow us to unblock the release of Spark that, up to this point, ships with a non-functional evaluation license of JxBrowser.
