It can be also written as: `return ClassFile.of().transform(classModel, ClassDesc.of(newClassName), ClassTransform.ACCEPT_ALL` But be aware this code does not change the class name use anywhere in the code, descriptors, handles, annotation, etc..., just the class name itself. Full class remapping was a job of https://docs.oracle.com/en/java/javase/23/docs/api/java.base/java/lang/classfile/components/ClassRemapper.html which unfortunately didn't make it from 23 preview to 24 :( ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/25857#discussion_r2169481261
