[jira] [Commented] (GROOVY-10405) @AutoClone breaks in Java17 for File properties

["Eric Milles (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-10405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17500857#comment-17500857 ] 

Eric Milles commented on GROOVY-10405:
--------------------------------------

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}}.

>  
> {code:java}
> import groovy.transform.AutoClone

> def foo = new Foo(file: new File('bar'), string: 'qux')
> foo.clone()
