Without Java3D, creating a new JFrame without setting it to visible will not prevent that code from exiting, just tried that... Java3D can create thousand threads for all I care, as long as everything goes away when it's done ;-)

Will probably open a ticket in our own JIRA to switch to another 3D Framework. *shrug*
