Bug#466538: gij-4.3: reflection on annotation objects throws IllegalAccessException

[Marcus Better <marcus@better.se>]

Package: gij-4.3
Version: 4.3-20080202-1
Severity: normal

The following test program throws an IllegalAccessException with gij,
but works with Sun Java.

~$ gij InvokeAnnotationMethod
Exception in thread "main" java.lang.IllegalAccessException
   at java.lang.reflect.Method.invoke(libgcj.so.90)
   at test.Helper.invoke(Helper.java:11)
   at InvokeAnnotationMethod.main(InvokeAnnotationMethod.java:11)

~$ java InvokeAnnotationMethod
~$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0-b105, mixed mode)

The odd thing is that if the test.Helper class below is moved up to
the default package, the program works. So there seems to be some
reflection bug.

------------------------- file InvokeAnnotationMethod.java ----------------
import java.lang.annotation.*;

import test.Helper;

public class InvokeAnnotationMethod
{
    public static void main(String[] args)
        throws Exception
    {
        Annotation ann = Inner.class.getAnnotation(Ann.class);
        new Helper().invoke(ann);
    }

    @Retention(RetentionPolicy.RUNTIME)
    public @interface Ann {
        public int param() default 0;
    }

    @Ann
    public class Inner
    {
    }
}
-------------------------------------------------------

------------------------- file test/Helper.java ----------------
package test;

import java.lang.reflect.Method;

public class Helper
{
    public void invoke(Object a)
        throws Exception
    {
        Method m = a.getClass().getMethod("param", new Class[0]);
        m.invoke(a, new Object[0]);
    }
}
