Hi Spencer,
The first Exception is bug
4467858 - GeometryArrayRetained getDlistTimeStamp() throws
ArrayIndexOutOfBoundsException
which is already fixed in v1.2.1_02, please upgrade your
Java3D version. You're right, the second one is bug
4359764 Java3D do not support > 32 canvas

>INFO / BACKGROUND
>This part of my program is in the form of MDI application with MenuBar
>and ToolBar with a JDesktopPane for a load of JInternalFrames which
>contain a canvas 3D.
>
>I find that is I add more than 4 internal frames, the entire application
>crashes / locks up giving that stacktrace with no reason I can find.. I
>guess that it might be a bug in java3d as a result of me approchign the
>problem in the wrong way.
>
>For each JInternalFrame I have added a Canvas3D. Each Canvas3D has a
>separate SimpleUniverse associated with it and the MouseBehaviors for
>rotate and zoom are attached to the single main BranchGroup. Onto each
>branchgroup I draw "myObject".
>
>This is where the problem arises by adding my complicated object into
>the universe on the canvas.
>
>I've done some testingon the content of the JinternalFrames
>If I just create them and add a simple JLabel to the frames.. I can keep
>creating > 50 frames ad inifintum*
>
>If I do frame.getContentPane().add(new
>javax.media.j3d.Canvas3D(null)); blank canvas3d I can open 32frames
>and I get error on the 33rd frame. The following also happens when I
>add a canvas3d with a simple universe.
