Description

@Grab(group='commons-primitives', module='commons-primitives', version='1.0')
import java.lang.annotation.*

@Retention(RetentionPolicy.RUNTIME)
@interface Require {
    String value()
}

The code above produces a class that is invalid and whose loading fails with the error below:

Caught: java.lang.VerifyError: (class: Require, method: <clinit> signature: ()V) Empty code

It seems that the static initializer method (<clinit>) gets written in bytecode without its body.
