springboot @Validated class calls with suspend functions throw ArrayIndexOutOfBoundsException

If you mark a class as @Validated and at the same time you use suspend functions inside the class (kotlin compiler generates a "Continuation" parameter for such methods) on any call for that class' methods you will see the exception below. Spring Boot Version: 2.2.6.RELEASE
