[jboss-jira] [JBoss JIRA] Commented: (JASSIST-42) Proxy serialization looses inner data objects
[
https://jira.jboss.org/jira/browse/JASSIST-42?page=com.atlassian.jira.plu...

Andrew Dinn commented on JASSIST-42:
------------------------------------
I have attached a patch against the current trunk to the forum thread mentioned in my last
comment which
1) makes serialization use the cache correctly
2) provides an alternative way to serialize objects using subclasses
ProxyObjectOuptut/InputStream of classes ObjectOuptut/InputStream.
This patch requires a minor change to javassist clients. They must no longer call
ProxyFactory.setHandler(). Instead they must cast each newly created proxy instance to a
ProxyObject and call method setHandler() on the proxy instance.
Proxy serialization looses inner data objects
---------------------------------------------
Key: JASSIST-42
URL: https://jira.jboss.org/jira/browse/JASSIST-42
Project: Javassist
Issue Type: Bug
Reporter: Damien Lecan
Assignee: Shigeru Chiba
Priority: Blocker
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 ...
