This comes from Eric Klopfer (###@###.###):

On the subject of 1.4.1, this actually has introduced a bit of a bug
in our application on certain computers. On some computers running
with jre 1.4.1, our application totally hangs the computer (though on
1.4.0_1 it works just fine). We've been stumped on what could cause this.
there someone that we could contact?
