Hi, with JBM shipped with JBossAS 5.1.0, i suspect that ObjectMessage body instances are cached. In a transaction I modify my object issued from ObjectMessage.getObject(), then something goes wrong and I do rollback on the JMS session. When the broker send the message a second time I get the same instance as the first failed receive with modifications made on my object in the previous failed transaction, It is not what I expect. So my question is : is this normal behaviour? Can I disable this cache and have everything rollbacked and my object deserialized again? Thank you for your help.
