It is a good time to jump to Java 11. It may not be too difficult getting the code to run per se, unless you are using CORBA and some really old tech. It would also be a good idea to invest some time into the launcher scripts and modular packaging in your application. However, it is high time you consider taking up a non Oracle distribution if you are looking for support.
