I started looking at Java 9 support. The first issue I faced is a bug in IntelliJ that prevents me from compiling in IDEA. Using the command line for now. The next is that AutoCompleteCombobox is using a lot of now internal classes, so the current approach is a no-go. It's going to need a lot of rewriting. I'll rename the file to .ktx for now and just ignore it to be able to work on other issues.
