Sean,
Thanks for your test program. We can reproduce the
bug and
4717253 -
D3D: May crash in buildGA when texture is not used under JDK1.3.1
is submitted for it.
It is caused by env->ReleasePrimitiveArrayCritical(..)
without checking NULL arguments in native code.
There are 2 workarounds:
(1) Use JDK1.4.1
or
(2) Under JDK1.3.1, use
java -Dj3d.displaylist=false apps
Note:
Although only OpenGL support displaylist,
in the Java layer it is still optimize for OpenGL by building
displaylist which may consists multiple primitive call.
In case DirectX version, the underlying native code is
handle by building a link list of VertexBuffer for a single
displayList ID defined in the upper java layer. Additional
optimization is done by merging primitive of the same type
in the neighbourhood of the link list.
It will be fixed in the next release.
Thanks.
- Kelvin

com.sun.j3d.utils.geometry package), which I think uses GeomBuffer QuadStrips
that are turned into a TriangleStripArray.
