... Only slightly more information, not all that helpful.
I have not been completely sure about whether or not this really was a case of 
pass-by-reference vs. pass-by-value within the container. When I run my JBoss 
tests, I notice some strange behavior in the application as well as the 
NotSerializableException mentioned above. Well, by coincedence, someone was 
running our WebSphere-based version of the same application the other day and 
the WebSphere app was showing the same strange behavior and the same 
NotSerializableException for the same class. The solution in this case was to 
go to Admin console to the ORB Service configuration for the app and to turn on 
pass-by-reference (it had gotten turned off somehow). After restarting the app 
server, the WebSphere app started working normally again. Now I am thinking 
that this really is a problem with pass-by-value/reference in JBoss.
 
I have read that JBoss is supposed to, by default, use pass-by-reference for 
method calls between EJBs  within the container. I looked at the 
org.jboss.invocation.InvokerInterceptor (I cannot remember what led me there) 
and I saw that it looks like it is trying to do the right thing with a local 
call. I am wondering what I might have done (or not done) to cause JBoss to not 
use pass-by-reference in this case. I am still looking for the solution. Please 
let me know if someone needs more information from me or examples of my code or 
configuration.
 
Thanks all.
