Comment From: snicoll

The log field is not created by @Log so that sounds like a regression in Groovy. We're not going to update and I've added this version to the ignore list.

Comment From: snicoll

With the help of @wilkinsona, we've identified the specific regression and we feel that we could change that particular sample and use the latest version rather than being stuck.

Comment From: wilkinsona

The problem can be reproduced with the following standalone Groovy script:

import groovy.util.logging.Log
import java.lang.reflect.Method
import java.util.function.Consumer
import net.sf.cglib.proxy.MethodInterceptor
import net.sf.cglib.proxy.MethodProxy
import net.sf.cglib.proxy.Enhancer

@Log
@Grab("cglib:cglib:3.3.0")
class Thing {
