[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1277) Object isolation verification
[ http://jira.jboss.com/jira/browse/JBMESSAGING-1277?page=comments#action_1... ]
Clebert Suconic commented on JBMESSAGING-1277:
----------------------------------------------
The only situation in which Object isolation would be broken is if you called
objectMsg.getObject(),
or if you called objectMsg.setObject(msg) twice.
On the first case, the returned object would have a shared reference, what means any calls
to the object after setObject will also change the object sent.
On the second case, if you called objectMsg.setObject(msg) twice, the second call would be
ignored.
This is not a common user's practice. As long as users avoid this behavior, they
should be fine.
Object isolation verification

Key: JBMESSAGING-1277
URL: http://jira.jboss.com/jira/browse/JBMESSAGING-1277
Project: JBoss Messaging
Issue Type: Bug
Affects Versions: 1.4.1.CR1, 1.4.0.SP3.CP02
Reporter: Clebert Suconic
Assigned To: Clebert Suconic
Priority: Minor
Fix For: Stable branch
Attachments: patch.diff
I believe there is a bug on ObjectMessage as reported by an user.
On the patch attached there is a testcase validating the Object isolation.
IMO an ObjectMessage shouldn't cache serialized objects, and it should aways return a
new de-serialized object. It is user's responsibility to proper manage calls to
getobject in order to not cause performance issues and excessive serialization on this
case.
