From talking with Paul about this situation, it sounds like we
currently do allow direct passivation of the nested stateful beans,
without passivating the top level bean that might reference it.
Up to now, I thought that we always passivated the top level stateful
bean and all referenced beans, as a group. We actually do passivate the
entire group (top level + nested beans), when the top level bean is
passivated but we also allow the nested beans to passivated in an
My question at this point is, could we switch to only passivating top
level beans? I'm not sure if we know the difference between top-level
and nested beans, which might make this difficult or impossible.

Just to keep everyone in the loop, it seems like configuring the
passivation max-size to be less than "one + number of nested beans",
could be the cause. We are currently configuring the passivation cache
max-size to be one, which may lead to passivation of the nested bean.
In the PassivationTestCase test, each top level session bean has a
nested bean. The top level bean shares the extended persistence context
with the nested bean.
If users hit this same failure, they should ensure that max-size is at
least equal to "1 + number of nested beans referenced from top level bean".
We will continue to discuss this case on IRC or email and keep you all
