[jboss-jira] [JBoss JIRA] (JBRULES-3644) Scheduled Activations are not fired after unmarshalling

[Philipp Herzig (JIRA)]

     [ https://issues.jboss.org/browse/JBRULES-3644?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Philipp Herzig updated JBRULES-3644:
------------------------------------

    Description: 
Currently, Scheduled Activations are not fired after they got unmarshalled from a binary. Although they reside on the agenda after unmarshalling, they have somehow an "orphan" status that leads to inconsistent state of the rule engine in general. As subsequent problem, deleting the rule that caused these "orphan" scheduled activations leads to a NPE when removing the timer job.

java.lang.NullPointerException

A detailed description can be found here: http://drools.46999.n3.nabble.com/rules-users-Protobuf-Marshaller-Question-ScheduledActivation-Persistence-td4019537.html

The attached test has been reworked to simply persist the session blob to a local file rather than a database. I should be easy to import as maven project.

Currently, Scheduled Activations are not fired after they got unmarshalled from a binary. Although they reside on the agenda after unmarshalling, they have somhow an "orphan" status. Therefore, also the engine runs in an inconsistent state since deleting the rule that caused these "orphan" scheduled activations leads to a NPE when removing the timer job.
