> This error occurs only some of the time, which leads me to believe there is a threading
issue here.  Specifically, looking at the following code fragment in {{org.apache.openejb.core.stateless.StatelessInstanceManager.getInstance(StatelessInstanceManager.java:111)}}:
> {code}
>                 Context ctx = deploymentInfo.getJndiEnc();                
>                 SessionContext sessionContext;
>                 try {
>                     sessionContext = (SessionContext) ctx.lookup("java:comp/EJBContext");
>                 } catch (NamingException e1) {
>                     sessionContext = createSessionContext();
>                     // TODO: This should work
>                     ctx.bind("java:comp/EJBContext", sessionContext);
>                 }   
> {code}
> It could be perhaps that the "java:/comp/EJBContext" is not initially found, but another
thread creates it by the time it is attempted to be bound in the last line.  Unfortunately,
I do not have a reproducible test case at the current time.
