Hello

It's a matter of SPI, something is missing in the directory "META-INF" or it's pointing to the wrong class or the classpath is correct but missing.

java3d-utils-1.7.2.jar/META-INF/services/org.jogamp.java3d.GeometryService contains:
org.jogamp.java3d.utils.geometry.GeometryServiceImpl

GeometryServiceImpl.class is in java3d-utils-1.7.2.jar

The matter doesn't come from Java3D, it comes from your use, java3d-utils should be in your classpath. This is not a bug for sure. When you create your standalone JAR, you have to include the whole content of all necessary dependencies, including the content of META-INF and all necessary classes.
