> Some core reflection APIs look for methods in classfile format that are 
> expected to be present from the Java compiler. These APIs are: 
> `Class.getEnclosingMethod`/`Constructor` and `RecordComponent.getAccessor`.
> 
> Currently, the Class ones throw `InternalError`, and the RecordComponent one 
> returns null. These are not suitable behaviors as `InternalError` indicates 
> an unrecoverable VM error, and a null return can propagate the error 
> downstream and is not informative.
> 
> I propose to make these methods all throw `NoSuchMethodError`, a subtype of 
> `LinkageError` and `IncompatibleClassChangeError`, which more accurately 
> reflects the cause of these scenarios. This is also more in line with other 
> failure modes of APIs like `Class.getDeclaringClass`, which throws 
> `NoClassDefFoundError`.
