RE: Error creating process w/ CORBA API

I'm sorry about this message. The following piece of code works just fine.

Subject:	[shark] Error creating process w/ CORBA API
Using the Shark 1.0 CORBA api, running on a windows machine, I was able to instantiate a process with the following piece of code:

ExecutionAdministration execAdmin = workflowServer.getExecutionAdministration();
execAdmin.connect(username, password, "", "");
WfProcessMgr mgr = execAdmin.getProcessMgrByName(procDefName);
WfProcess proc = mgr.create_process(new MyRequester());

After migrating to Shark 1.1 running on a Linux machine, the last line always fails with the following stack trace:

Below is the source code for MyRequester:

import org.omg.CORBA.portable.ObjectImpl;
import org.omg.WfBase.BaseException;
import org.omg.WorkflowModel.*;
import java.util.*;

public class MyRequester extends ObjectImpl implements WfRequester {
        private List performers = new ArrayList();
        private static String[] __ids = { "IDL:omg.org/WorkflowModel/WfRequester:1.0", "IDL:omg.org/WfBase/BaseBusinessObject:1.0" };
        public String[] _ids() { return (String[]) __ids.clone(); }
        public int how_many_performer() throws BaseException { return performers.size(); }
        public WfProcessIterator get_iterator_performer() throws BaseException { throw new BaseException(); }
        public WfProcess[] get_sequence_performer(int max_number) throws BaseException {        return (WfProcess[]) performers.toArray(new WfProcess[performers.size()]); }
        public boolean is_member_of_performer(WfProcess member) throws BaseException {  return performers.contains(member); }
        public void receive_event(WfEventAudit arg0) throws BaseException, InvalidPerformer { throw new BaseException(); }
}

Any hints, anyone? Is the MyRequester code correct?
 
Notes: I'm using the default HSQL database. I already tried disabling cache. I even tried to disable security (NO_SECURITY).
 
Thanks in advance,
    Leonardo
