Re: java.lang.ClassNotFoundException: javax.sql.DataSource when using GWT 2.9.0 + Java 11 combination

Thanks Jens for your quick help. I appreciate it.

Without being able to see the project setup this is tough to answer.

However regardless of the exception you are seeing: Classic/Legacy DevMode will not work with GWT 2.9.0 correctly, because GWT 2.9.0 already uses JsInterop internally in its Java SDK emulation (e.g. java.util.Date uses it). JsInterop is not supported by classic/legacy DevMode. With GWT 2.9.0 you have to use SuperDevMode to have a functional Java SDK emulation during development.
