Hi Charith
Did you take a look at the unit tests in directory client/src/test/java in
package org.apache.qpid.test.unit.client.message?
I think the addition of a 'pure' unit test, rather than an extension to the
system test would be more appropriate. I'd imagine we'd want a unit test much
like client's BytesMessageTest, which would exercise the happy paths
(serialised class, serialised primitive) and the maybe the unhappy path
(serialised class not found through I can see this might be tricky).
I took a look at your extension to the system test ObjectInputStream. Does the
test using CustomSerializableObject give us anything more than the existing
tests with ObjectMessageTest.Payload?
Hope this helps.

> Hi ,
> When we are using qpid client to receive JMSObject in complex class loading
> environments like web application containers/Osgi environments .There is a
> scenario where this issues comes.
> Scenario.
> In a web application container normally they use a class loader per web app.
> and if we have qpid client libs at the root classloader level this error can
> come. The reason for this is Serializable Object types that are used inside
> the web app are not visible to the class loader that loads the JMSObject
> message and unmarshall it.
> thanks,
> Charith
