[JAVA3D] Java3d 1.3

[Denis Troller]

I've tried to install the beta release of Java3D 1.3, but when I sometimes get this exception : java.lang.NullPointerException     at javax.media.j3d.MasterControl.createUpdateThread(MasterControl.java:1677)     at javax.media.j3d.MasterControl.registerView(MasterControl.java:2343)     at javax.media.j3d.MasterControl.handlePendingRequest(MasterControl.java:2863)     at javax.media.j3d.MasterControl.doWork(MasterControl.java:2787)     at javax.media.j3d.MasterControlThread.run(MasterControl.java:28)   I never had such problem with 1.2. Does anybody have any idea where this might come from ?   Denis
