There is no need to create a thread, rather use an animator. GLEventListener instances can but shouldn't be used that way. Rather create a single GLEventListener, add it once for all into the canvas and this single GLEventListener should loop on all objects. These objects should have some drawing code.

You can use a scenegraph API instead of reinventing the wheel except if you want to use only JOGL.

Edit.: You shouldn't have to swap the buffers by yourself especially if you haven't called setAutoSwapBufferMode(false). The more you go away from the helpers of a framework, the more you become responsible for doing the things the "right" way.

Edit.2: You can look at this very simple example.
