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

[green at redhat dot com]

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

Wasn't this fixed on the 4.0 branch by sorting the files
passed to the BC compilations?

If so, on the trunk we should probably instead look at the libtool fix.

Yes, that's right.

Yes, that's what we discussed before.

I'm testing a patch for this.
I didn't fix libtool but instead changed how we perform these compilations.

I checked in a fix on the trunk.
I think this is already fixed on the 4.0 branch.
