[Bug libgcj/21058] New: libgcj can't find class

["green at redhat dot com" <gcc-bugzilla@gcc.gnu.org>]

Given the following test program:

---- cut here -------------------------------------------
import java.awt.*;
import javax.imageio.*;

public class ShowJPEGReader
{
    public static void main (String args[])
      {
        System.out.println (Toolkit.getDefaultToolkit ());
        System.out.println (ImageIO.getImageReadersByFormatName("JPEG").next());
      }
}
---- cut here -------------------------------------------

Running it results in:

$ gij ShowJPEGReader
gnu.java.awt.peer.gtk.GtkToolkit@55e00

But javax.imageio.ImageIO$ReaderMIMETypeFilter is here:
