Hi Santiago,

Thanks for the stack dump. You've found a VisAD bug. There's a
candidate fix in the visad_src-2.0.jar and visad.jar files at:

  ftp://ftp.ssec.wisc.edu/pub/visad-2.0/untested/

Please try:

            display.destroy();
            display.stopThreadPool();

again and let the list know if this does not solve your problem.

Cheers,
Bill
