Is *expected*. You need to update to the 2.4.0 rc to get rid of that. (Oracle and the OpenJDK project have been working to remove access to many of these sun.*.* Packages since Java 9 - they were never officially supported, and they want to be able to remove or change them in breaking ways - which is also why you don't get the warning on Java 8. - at that point, they didn't care)

As someone who has worked through some of this transition with another application:

- update to the latest library
- recompile your application against the new library, using the oldest version of Java that you want to support

There seem to be a few places where the Fully Qualified Classname/Method name that the compiler generated when compiling against the old library causes issues when run against the new. (Weird exceptions, etc)
