---------------------------------------------------------------
The issue lies in {{AutoClone}}'s "super.clone()" call to start out the cloning
process. Under Java 17, the meta method index does not get {{methodForSuper}}
populated for clone. Using {{@CompileStatic}} will create a direct method call
in the bytecode instead of routing through
{{ScriptBytecodeAdapter#invokeMethodOnSuper0}}.
There was a significant overhaul of the super method indexing for Groovy 4. It
is not safe to backport this to Groovy 3.
