Unfortunately, the compressed geometry file format was developed externally to
Java 3D and is a structured file that requires random access, so it can't be
streamed from a URL. Applets can only access streams with the default
security, so this leads to the security violations.
I've submitted a Request For Enhancement (RFE 4374631) to address this issue.
I would prefer implementing Serializable for CompressedGeometry, but other
possibilities include adding a CompressedGeometryFile constructor that accepts
InputStream while ignoring the object directory and disallowing random access,
or perhaps a new CompressedGeometryStream class.
