Bug in Sun compiler?

[adrian.brock]

I found this while looking at a microcontainer test.

It fails in both JDK5 and JDK6, but works with eclipse.

Looks like a bug to me? Anybody confirm?

package test;

import java.lang.reflect.Constructor;
import java.lang.reflect.Type;
import java.util.Arrays;

public class Main
{
 public static void main(String[] args) throws Exception
 {
 Class<MyEnum> clazz = MyEnum.class;
 Constructor<MyEnum> constructor = clazz.getDeclaredConstructor(new Class[] { String.class, Integer.TYPE });
 Type[] types = constructor.getParameterTypes();
 Type[] generic = constructor.getGenericParameterTypes();
 System.out.println("types = " + Arrays.asList(types));
 System.out.println("generic = " + Arrays.asList(generic));
 if (Arrays.equals(types, generic) == false)
 throw new RuntimeException("They should be the same?");
 }

 public enum MyEnum { ONE, TWO, THREE };
}

Sorry I post there.

types = [class.java.lang.string, int]
generic = []
Exception in thread "main" java.lang.RuntimeException: They should be the same?

my config fedora5 + NetBeans 5.5 + jdk 6

Its a known bug for inner classes that has been open for some time:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5087240

although, even if I pull the enum into a separate class I still see the same problem.

I originally found it with a standalone enum.

I've reported it as a bug. I did find a bug report that asked
for the opposite in apt (don't show the synthetic parameters)
so I guess they hacked the compiler to not annotate the class properly. :-)
