Thank you folks for your help. Here in attachment you'll find two
compressed files, one with the Eclipse project (use File->Import) and
another with the plain java files.
Don't try to find much logic in it, it is a very stripped down version
of another simulation, just for illustration.
Thank you once more,

So if you're having a problem at this point either there's a bug in your code or a bug in ours. To determine this, I will need you to send me (directly) a tarball containing an ideally simple example of the bug happening, including source code, so we can poke around.

Or you have the object being added to the field somehow or it's part of some other field which is being drawn.
