Re: Crash system - DUMP File generated with OJB

Hi,

We don't modify any in ojb source classes , we use the binary ojb from
apache.

here is our mapping related to classes habilitations :

Hi,

I tested the implementation of class ReferenceMap - it works as
expected. In class AnonymousPersistentField the persistent object is
used as map key, the field value (of the anonymous field) as map value
and the ReferenceMap use weak keys and hard values, thus all persistent
objects set in class AnonymousPersistentField should be GC (if the
persistent object was no longer referenced) - in theory this should
work, but it seems this doesn't work for you.

Could you please post the mapping of the involved classes MotdePasse and
Utilisateur (and of mapped sub/super-classes of these classes if any
exist).
Do you modify any source classes of OJB related to anonymous fields or
references?

regards,
Armin
