 So passing nullable type as a type argument or type parameter produces a warning.
 
 Annotating type arguments and type parameters works with the Java 8 target or higher. The feature requires that the 
-nullability annotations support the `TYPE_USE` target (`org.jetbrains.annotations` supports this in version 15 and above). 
-Pass the `-Xtype-enhancement-improvements-strict-mode` compiler option to report errors in Kotlin code that uses 
-nullability which deviates from the nullability annotations from Java.
