Building Native Java 3D (j3d) from Sources ?

[Dr. Gary E. RAFE]

Anyone on this list have any success building a native Java 3D ?

Using FreeBSD 6.2-R, XFree86-4.7.0, NVIDIA-96.43.01, JDK-1.5.0._13p7
on a Toshiba Satellite Pro 6100 notebook.

Fetched current Java 3D (1.5.2 beta1)
sources (vecmath, j3d-core, j3d-core-utils)
from CVS at java.net, and built JARs for these projects,
along with the i386 shared library libj3dcore-ogl.so
by adding appropriate ant(1) build files for freebsd-i386.

With the JARs and shared library installed in .../jre/lib/
as appropriate, the Java 3D program "Package Info" reports:

$ CLASSPATH=dist/j3d-examples.jar \
java org.jdesktop.j3d.examples.package_info.PackageInfo

Package Info window:
package javax.vecmath, Java 3D API Specification, version 1.5
Specification Title = Java 3D API Specification
Specification Vendor = Sun Microsystems, Inc.
Specification Version = 1.5
Implementation Vendor = Sun Microsystems, Inc.
Implementation Version = 1.5.2

package javax.media.j3d, Java 3D API Specification, version 1.5
Specification Title = Java 3D API Specification
Specification Vendor = Sun Microsystems, Inc.
Specification Version = 1.5
Implementation Vendor = Sun Microsystems, Inc.
Implementation Version = 1.5.2

package com.sun.j3d.utils.universe, version 1.5
Specification Title = 
Specification Vendor = Sun Microsystems, Inc.
Specification Version = 1.5
Implementation Vendor = Sun Microsystems, Inc.
Implementation Version = 1.5.2

The Java 3D program "Hello Universe", however, fails:

$ CLASSPATH=dist/j3d-examples.jar \
java -Dj3d.debug=true org.jdesktop.j3d.examples.hello_universe.HelloUniverse

Java 3D [dev] 1.5.2-pre2-0802011144-experimental 01 Feb 2008 11:44:30 EST

Java 3D: J3dDebug.debug enabled
Java 3D: concurrent threadLimit = 2

I get the same result regardless of the maximum Java heap size,
so something else must be at play here.
[Oh, so close...]

Observations ?  Suggestions ?  Pointers ?
