Description

Annotation properties of array type are generated with null walue in java stubs. Subsequently, stub compilation fail.

For example :

// ArrayAnnotation.java
public @interface ArrayAnnotation {
String[] value() default {};
}

// AnnotatedClass.groovy
@ArrayAnnotation(["foo", "bar"])
class AnnotatedClass { }

generates the stub :

@ArrayAnnotation(value=null)
public class AnnotatedClass extends java.lang.Object implements groovy.lang.GroovyObject {
// irrelevent stuff removed
}

Compilation fails with the message :

Compilation failure: \...\target\generated-sources\groovy-stubs\main\groovystubs\AnnotatedClass.java:[4,23] attribute value must be constant
