gcj 1.5.x: error: /classname/ cannot be resolved to a type

Hi there,

  I am getting an error using gcj 1.5.x I was not getting in older
release, and I do not understand what I am doing wrong.

  Compilation line:

cd /home/mathieu/Perso/gdcm/debug-snap/Utilities/VTK/java &&
/usr/lib/gcc-snapshot/java-1.5.0-gcj-4.5/bin/javac -cp
/home/mathieu/Kitware/VTK-snap/bin/vtk.jar vtk/*.java
gcj: warning: already-compiled .class files ignored with -C
vtk/vtkGDCMImageReader.java:5: warning: The import vtk is never used
  import vtk.*;
         ^^^
vtk/vtkGDCMImageReader.java:7: error: vtkMedicalImageReader2 cannot be
resolved to a type
  public class vtkGDCMImageReader extends vtkMedicalImageReader2
                                          ^^^^^^^^^^^^^^^^^^^^^^


With:

$ /usr/lib/gcc-snapshot/java-1.5.0-gcj-4.5/bin/jar  tvf
/home/mathieu/Kitware/VTK-snap/bin/vtk.jar | grep
vtkMedicalImageReader2
 2990 Wed 7 08 10:54:20 CEST 2009 vtk/vtkMedicalImageReader2.java
 3023 Wed 7 08 10:54:22 CEST 2009 vtk/vtkMedicalImageReader2.class


Copy of the java code:

...
$ head ./Utilities/VTK/java/vtk/vtkGDCMImageReader.java
// java wrapper for vtkGDCMImageReader object
//

package vtk;
import vtk.*;

public class vtkGDCMImageReader extends vtkMedicalImageReader2
{

  private native String GetClassName_0();
...
