While moving Spark to Maven JxBrowser plugin has been added to the source to improve browser feature (used for co-browsing and probably Ofmeet plugin). But it has complicated license requirements. So it should be replaced with an analogue. Java CEF is the choice currently.
As Jcef is not going to be ready for replacement for quite some time, the choice was made to stick to JxBrowser and add disclaimer to the readme. If we ever replace it with jcef, we should also remove that disclaimer. removed
