[GROOVY-9096] Repeatable annotation not wrapped with container type in class file

• Type: Bug
• Status: Closed

• Affects Version/s: 2.5.6

• Component/s: Compiler

Description

Consider the following:
Anno.java

import java.lang.annotation.*;

@Retention(RetentionPolicy.CLASS)
@Repeatable(Annos.class)
@interface Anno {
  String value() default "";
}

@Retention(RetentionPolicy.CLASS)
@interface Annos {
  Anno[] value();
}

Pogo.groovy

@Anno @Anno('x')
class Pogo {}

When this is compiled, the annotations in the class file are incorrect:

// Compiled from Pogo.groovy (version 1.8 : 52.0, super bit)
@[e-mail](value="x")
public class Pogo implements groovy.lang.GroovyObject {

vs.

// Compiled from Pojo.java (version 1.8 : 52.0, super bit)
@Annos(value={@Anno,@Anno(value="x")})
public class Pojo {

See GROOVY-8234 for initial support for @Repeatable.
