Annotation class values not retained correctly

Issue #13 resolved
Jesper Öqvist created an issue

Class values in annotations are not retained correctly for annotation types with runtime retention policy.

Test case:

import java.lang.annotation.*;
import java.lang.reflect.*;

public class Test {
    @Retention(RetentionPolicy.RUNTIME) @interface Testable { Class value(); }

    @Testable(Test.class) public void m() { }

    public static void main(String[] args) throws Exception {
        Method[] methods = Test.class.getDeclaredMethods();
        for (Method m: methods) {
            if (m.getName().equals("m")) {
                Object annotation = m.getAnnotation(Testable.class);
                System.out.println("annotation: " + annotation);
                Testable t = (Testable) annotation;
                System.out.println("value: " + t.value());

Expected output:

annotation: @Test$Testable(value=class Test)
value: class Test

Actual output when compiled with JastAddJ 7.1.1-46-g0cd3fe5 Java SE 7:

annotation: @Test$Testable(value=class java.lang.Class)
value: class java.lang.Class

  1. Jesper Öqvist reporter

    The problem here is that the type descriptor for the class value is computed from the type of the class access expression, not the class access itself!

    Fixed annotation codegen bug

    • added attribute classAccess to compute the hostType of a class access
    • fixed error in annotation bytecode for Class-valued attributes
    • fixes #13
