[jboss-jira] [JBoss JIRA] Commented: (JASSIST-42) Proxy serialization looses inner data objects

[David Lloyd (JIRA)]

    [ https://jira.jboss.org/jira/browse/JASSIST-42?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12493917#action_12493917 ] 

David Lloyd commented on JASSIST-42:
------------------------------------

An additional comment to #2 - you'll definitely want to make sure you always use a constant value (like 0 or -1) for the generated class' serialVersionUID field.  Also, you may need to take steps to ensure that the generated class on the receiving side has the same package and name as the originating class; there is some check there but I don't recall if it is on the sending or receiving side, and what the exact restriction is.

> I working with proxies build with ProxyFactory method.
> When I want to serialize/deserialize it, everything seems to be ok except that only proxy instance is serialized, not inner objects.
> Eg.
> Object "A" contains an instance of "B"
> After serialization/deserialization of a proxy of A, instance of "B" in "A" is null
> When I look at this code :
> public static SerializedProxy makeSerializedProxy(Object proxy)
> throws java.io.InvalidClassException
> {
> Class clazz = proxy.getClass();
> return new SerializedProxy(clazz, ProxyFactory.getFilter(clazz),
> ProxyFactory.getHandler(clazz));
> }
> I don't understand how serialization can keep inner objects ...
