Hello Dominique,

You do not have to change anything, my patch works as is with
default-jdk on all architectures.  A similar fix has already been
applied months ago, see
   http://git.debian.org/?p=collab-maint/vtk.git;a=commit;h=db81316
We need this new one in VTK 5.6 because new files have been added into
Wrapping/Java/vtk/, and they use Java 5 features.  The previous fix
dealt with automatically generated Java files.

I do not know how to best "emulate" architectures which do not default
to openjdk; but you can try
  # rm /usr/lib/jvm/default-java
  # ln -s java-1.5.0-gcj /usr/lib/jvm/default-java
Do not forget to reset this symlink when you have finished ;)
