Andreas,
did you experience the problem when running JBoss from a command shell with no
CLASSPATH variable set (to make sure that no strange things, like the J2EE reference
implementation, screw things up...)?

The Singleton ORB could be used in applications or applets. The Singleton ORB is
really a crippled ORB with only limited functionality (e.g. creating typecodes).
Calling ORB.init(...) multiple times (at least with different configuration arguments,
e.g. different ORBNames) should return different ORB instances. This is not only
inefficient; it would also yield a faulty behavior at least if your doing this on the
serverside. A better approach would be to create a class that wraps your "fully
functional ORB" instance as a singleton.
