[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2453) Marshalling issue with not rules

[Jordi Alvarez (JIRA)]

    [ https://issues.jboss.org/browse/JBRULES-2453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12617214#comment-12617214 ] 

Jordi Alvarez commented on JBRULES-2453:
----------------------------------------

Just for completeness:

This problem was not specific to not nodes but also to exist nodes.

We are using version 5.1.1. In our situation, the write of the rete tree state enters in a infinite loop whenever:

- An exists node is reached which is blocked and has a child.
In this situation an infinite loop occurs in method OutputMarshaller.writeInitialFactHandleLeftTuples when persisting the exists node.

The changes already applied to OutputMarshaller class in the current development version fixed the problem for our situation.
