P.S. That method has an intentionally scary name, but behind the name, it’s just “asType, the JVM edition, plus narrowing primitive conversions”. The design center for asType is safe and sane conversions as allowed by variable assignment in Java, while the other guy adds all the other conversions that might be useful. If you know statically what is the input value type, as with BSMs working on CP data, then “explicitCastArguments” is just as safe as “asType” but it does more tricks for you.
