[GROOVY-7764] Joint compilation does not work with AST-transformed Groovy

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 2.4.6
• Component/s: Stub generator / Joint compiler

Description

When using AST transformations together with joint compilation the generated stubs don't mind the transformations, which may yield invalid classes, that javac will fail to compile.

Example:

[...]
class GroovyTest implements Callable {
    @Delegate
    private final Callable c = { println "Hello World" }
}

will get compiled into the following stub:

[...]
public class GroovyTest
  extends java.lang.Object  implements
    java.util.concurrent.Callable,    groovy.lang.GroovyObject {
;
public  groovy.lang.MetaClass getMetaClass() { return (groovy.lang.MetaClass)null;}
public  void setMetaClass(groovy.lang.MetaClass mc) { }
public  java.lang.Object invokeMethod(java.lang.String method, java.lang.Object arguments) { return null;}
public  java.lang.Object getProperty(java.lang.String property) { return null;}
public  void setProperty(java.lang.String property, java.lang.Object value) { }
}

which claims to implement Callable, but lacks a call method.

I don't know if this is specific to @Delegate, but noticed similar behaviour with @InheritConstructors.
