[jboss-jira] [JBoss JIRA] (DROOLS-35) Possible memory leak: MarshallerReaderContext held indefinitely by ReteooStatefulSession

[Mario Fusco (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-35?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12753627#comment-12753627 ] 

Mario Fusco commented on DROOLS-35:
-----------------------------------

I cannot reproduce this issue. 
More precisely I cannot find any reference chain from the ReteooStatefulSession to the MarshallerReaderContext.
Could you please specify in more details how (with which field) the ReteooStatefulSession keeps a reference to the MarshallerReaderContext after the unmarshalling process?

> It seems that the memory consumption increases after a session has been unmarshalled. That is to say: an unmarshalled session of size x uses  much more memory than if I had started with an empty session and inserted x number of facts.
> Digging into a memory profile, I found that after unmarshalling, my ReteooStatefulSession instance holds on to a MarshallerReaderContext instance. The MarshallerReaderContext consumes a lot of memory.
> Digging into the unmarshalling code, it seems that the MarshallerReaderContext is a utility class used during unmarshalling of sessions. Intuitively, it seems wrong that a reference to this object should be held after unmarshalling is finished.
