jAlbum 17.1 beta is out . I've added Groovy 3.0 Alpha to it, which now runs on Java 11 and has a true Java-like syntax for those of us that don't want to re-learn. With Groovy there's a potential for faster album processing than with BeanShell as Groovy scriptlets gets compiled under jAlbum 17.1. Groovy also supports modern-day Java constructs, like lambda expressions for instance. Check out this sample code that responds to a button press:
b = new JButton("A button")
add b // Add it to the container
b.addActionListener { b.text="Im clicked" }
