Open Source Java Libraries for Linux

Most developer’s wish list probably hosts the idea of exploring new ways of decorating his/her applications window... Of course, preferences of current OSes do propose a few options, but some may want more, or different choices, would it just be to frame their apps with their own uniform “branded” style. FXWindowFramer is a quite simple JavaFX library, which may be used to change the look&feel of a JavaFX application (applying just a few cosmetic changes through CSS definitions), or, as a starting point, to investigate more advanced alternatives... To keep things simple and the prototype easy to understand, FXWindowFramer only touches the application window frame (borders and nameplate), and only supports, as such, desktop applications that do not need resizing. The goal is : Keep the painting intact, but change that frame, keeping it as simple and close to usual JavaFX initialization as possible!
