Note also that the reason why you are getting this exception here is 
because the Session is being accessed by a different thread 
("Replication Thread" from ehcache) and is violating the single-thread 
requirement about accessing the client-stub to mulgara. This is stemming 
from the fact that the cache is containing objects with associations 
that are yet to be loaded (as mentioned in the previous e-mail).


Cheers,
