warning: missing type argument to method asInstanceOf
java.lang.ClassCastException: class java.lang.String cannot be cast to class scala.runtime.Nothing$ (java.lang.String is in module java.base of loader 'bootstrap'; scala.runtime.Nothing$ is in unnamed module of loader 'bootstrap')
... 30 elided
Edit: I misread “hit by this” as “bit by this”.
