paolo di tommaso updated GROOVY-11389:
--------------------------------------
Description:
Context: Java 21 introduces a new interface SequencedCollection
as super-interface for `List` and other interfaces.
This causes an issue in Groovy when the following conditions are met:
1. Using a `@Delegate List someAttribute` in a class
2. Compile with Java 21
3. Run with Java 20 or earlier the resulting app.
