Greetings Siegmar; sorry for the horrid delay in replying. :-(
Ralph opened a ticket about this a while ago
(https://svn.open-mpi.org/trac/ompi/ticket/3351). I answered it this morning
-- see the ticket for the details.
Short version: I don't think that your program is correct.

Hi,
I have built openmpi-1.9a1r27380 with Java support and try some small
programs. When I try to scatter an object, I get a ClassCastException.
I use the following object.
public class MyData implements java.io.Serializable
{
static final long serialVersionUID = -5243516570672186644L;
