[rules-users] Synchronization requirements on newStatelessKnowledgeSession()?

Are there any synchronization requirements on calling knowledgeBase.newStatelessKnowledgeSession()? Must I synchronize on anything to make this call in a multithreaded environment? Once I have a StatelessKnowledgeSession, must I synchronize on anything to work with it, or is it truly stateless in all regards? I'm not sure my previous message on this topic was received properly. Thanks, Laird
