---------------------------------
We need a failing test or at least pseudo-domain-classes,mappings and a chunk of code to see the exception.
Thanks.
check this link if you want provide a failing test

are you 100% that the case is the same ?
Sławomir can you check if your case is the same ?
Thanks.

Alexey Gorbach commented on NH-2510:
------------------------------------
According to given information - yes. Exception is the same, and it is thrown only when cache is turned on and when entity has lazy-load byte[] field.
Thanks.
P.S. Have you applyied patch ? Is everything OK with it ? Should I change something, if I post another test for another bug ?

-------------------------------------
My case is similar. The only difference is that I have cache declaration (with usage equal "read-only") in class mapping.
Thanks.
