Hi Tim,
From the line number, the version that you are using is still v1.2
Please upgrade it to J3D v1.2.1_01, if the problem still there,
please send us a test case.
Thanks.

>Hi,

>I have developed an application that uses Java3D, and I am finding an
>exception is thrown occasionally at start up. The stack trace output is as

>null renderer
>java.lang.NullPointerException
> at javax.media.j3d.MasterControl.updateWorkThreads(MasterControl.java:2095)
> at javax.media.j3d.MasterControl.doWork(MasterControl.java:2199)

>I am using Java2 1.3, and J3D 1.2.

>Any ideas as to what is causing this, and what I can do to fix it?
