Javalin with JPMS and ServiceLoader results in NoClassDefFoundError: kotlin/NoWhenBranchMatchedException

**Actual behavior (the bug)**

Running Javalin with JPMS and ServiceLoader leads to the a NoClassDefFoundError. If I run the very same application not as a module and without the service loader everything works just fine. 



**Expected behavior**

I'm expecting Javalin to work with JPMS and ServiceLoader the same way it does for a console application without Javalin. If you run the console application in the same project everything works out just fine.



**To Reproduce**



- (✓) Clone [no-jpms-and-serviceloader branch](https://github.com/baumgarb/javalin-with-jpms/tree/no-jpms-and-serviceloader) and you'll see everything works fine.



- (✓) Run console app in very same project and you'll see everything works fine as well with ServiceLoader and JPMS in place.

  ```

  .\gradlew.bat :client:run

  ```



- (✗) Clone [main branch](https://github.com/baumgarb/javalin-with-jpms/tree/main) and follow README.md to step 3 and you well end up with the exception:

  ```
