19991220: problems with Java3D/VisAD on Solaris SPARC


We're running into some problems running VisAD applications
on Solaris/SPARC with the latest 1.2.1 JDK and OpenGL 1.2.
Here are the particulars:

we're running:

laraine:/var/adm% java -version
java version "1.2.1"
Solaris VM (build Solaris_JDK_1.2.1_04, native threads, sunwjit)

laraine:/var/adm% what /usr/openwin/lib/libGL.so.1
        RELEASE VERSION: SUNWglrt Sun OpenGL 1.2 patch 108131-03 for Solaris, li
        bGL.so.1, sparc, October 27, 1999

The problem is that the VisAD apps cause java to core dump, in
particular when switching a display from 2D to 3D or vice/versa.
This also happens in the VisAD SpreadSheet, when switching from 2D to
3D in a cell, although it helps to have some data in the cell
for this to happen.  Perhaps it is a memory problem?

Is anyone else out there in VisAD land running the same versions
of  java and OpenGL and has found a similar problem?  Any
help would be appreciated.
