 IMHO that's the expected behaviour. I agree that it throws the
exception because the session bean Manager2 is creating a new jcr
session on each call, it causes that on the second call the new jcr
Session doesn't see the transient changes made by the previous one.

I think one possible fix is to create the jcr Session in Manager1 and
pass it as a parameter to Manager2.

Not sure, but I think that it probably worked before because you
probably closed the connection in Manager2 on each call, and on the
new call you got the same connection from the pool with the transient
changes in it because the session wasn't cleaned up correctly when it
was put back to the pool (JCR-461).
