NPE destroying Java3d component

Hi,

This happens infrequently and I believe I recall this from the pre-jogamp version 1.5.2 and earlier:

Error destroying java3d component
java.lang.NullPointerException
    at javax.media.j3d.NodeRetained.clearLive(NodeRetained.java:737)
    at javax.media.j3d.GroupRetained.clearLive(GroupRetained.java:2686)
    at javax.media.j3d.GroupRetained.clearLive(GroupRetained.java:2733)
    at javax.media.j3d.Locale.doRemoveBranchGraph(Locale.java:344)
    at javax.media.j3d.Locale.removeFromUniverse(Locale.java:313)
    at javax.media.j3d.VirtualUniverse.removeAllLocales(VirtualUniverse.java:358)

I'm using 1.6.0pre9

Of course, It's always easier growing a graph than paring it back.  I'm trying to plug memory leaks using Java3d

Any help appreciated, thank you to the developers and community contributors for keeping this alive.

Hi

Please use the very latest version (currently Java3D 1.6.0 pre 11) and provide a test case to reproduce this bug.

Edit.: We don't maintain Java3D 1.5.2 but your indication is helpful to know that it's not a regression of Java3D 1.6.

Same problem with 1.6.0pre11 and jogl2.2.4  Looks like NodeRetained's VirtualUniverse reference is set to null before expected.  I guess the question is who has access to NodeRetainded.universe and can set it to null.  Just to be clear, I'm no longer using Java3D 1.5.2, but I do remember this Exception.
