[Bug java/34444] New: Class.getEnclosingClass() returns null on enclosed class

[gcc-bugzilla at matthew dot ath dot cx]

Class.getEnclosingClass() returns null on enclosed class.

Specifically:

   c = class org.freedesktop.DBus$Local$Disconnected
   c.getEnclosingClass() = null

   (followed by a null pointer exception on the next line)

Code which prints that:

   if (Debug.debug) Debug.print(Debug.VERBOSE, "c = "+c);
        if (Debug.debug) Debug.print(Debug.VERBOSE, "c.getEnclosingClass() =
"+c.getEnclosingClass());
        if (Debug.debug) Debug.print(Debug.VERBOSE,
"c.getEnclosingClass().getAnnotation(DBusInterfaceName.class) =
"+c.getEnclosingClass().getAnnotation(DBusInterfaceName.class));
         if (null !=
c.getEnclosingClass().getAnnotation(DBusInterfaceName.class))

Source for DBus$Local$Disconnected:

public interface DBus extends DBusInterface
{

 ....

   /**
    * Messages generated locally in the application.
    */
   public interface Local extends DBusInterface
   {
      public class Disconnected extends DBusSignal
      {
         public Disconnected(String path) throws DBusException
         {
            super(path);
         }
      }
   }

  ....
}

GCC version:

gcc (GCC) 4.2.3 20071123 (prerelease) (Debian 4.2.2-4)

(Also happens in 4.2.2)

This code works as expected in Sun JDK 5 and 6

Here's a complete test case.
The .class file does have the InnerClasses attribute,
we just don't seem to read it properly.

public class p
{
  public interface DBI { }

  public interface Local extends DBI {
    public class Disconnected
    {
      public Disconnected()
      {
      }
    }
  }

  public static void main(String[] args) throws Throwable {
    Class c = Local.Disconnected.class;
    System.out.println(c.getEnclosingClass());
  }
}

Another case where Sun's javadoc was rather vague.
