Official Specifications for CORBA support in J2SE 1.4
http://java.sun.com/j2se/1.4/docs/api/org/omg/CORBA/doc-files/compliance.html

document says:
Section 11.3.7 POAs must preserve all policies.
"

But POA.create_POA() method throws NO_IMPLEMENT exeption
for the SINGLE_THREAD_MODEL policy.


See example:
------------- ORBTest.java ---------------------
import org.omg.CORBA.*;
import org.omg.PortableServer.*;
import org.omg.PortableServer.POAPackage.InvalidPolicy;

public class ORBTest {
                                                               
    public static void main(String argv[]) {
try {
ORB orb = ORB.init(argv, null);

POA rootPOA = POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
Policy[] policies = {
rootPOA.create_thread_policy(
ThreadPolicyValue.SINGLE_THREAD_MODEL)
};

POA testPOA = rootPOA.create_POA("Test", null, policies);
System.out.println("OKAY");
} catch(Exception e) {
System.out.println("ERROR : " + e);
e.printStackTrace(System.out);
}
    }

}
