A Java 3D program that defines an illegal scene graph may compile, but not render. When a Java 3D
program that defines an illegal scene graph is run, the Java 3D system detects the problem. When the
problem is detected, the Java 3D system will report an exception. The program may still be running and
consequently, needs to be stopped. However, no image will be rendered.
