[jboss-jira] [JBoss JIRA] (DROOLS-252) Deserialization with TimerJobFactoryOption causes NPE -

Deserialization with TimerJobFactoryOption causes NPE - -------------------------------------------------------- Key: DROOLS-252 URL: https://issues.jboss.org/browse/DROOLS-252 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 5.5.0.Final Reporter: Philipp Herzig Assignee: Mario Fusco In 5.5.0 the unmarshalling of a stateful sessions causes the following NPE trace when KnowledgeSessionConfiguration.setOption(TimerJobFactoryOption.get("trackable")); is set! This worked fine under 5.4.0 where the options was still set with ((SessionConfiguration) this.conf).setTimerJobFactoryManager(new TrackableTimeJobFactoryManager()); The error only occurs with the option set, no w/o it and iff temporal operators are present. In my cases I simply used a over window:time(x) operator. Steps to reproduce: 1. Create two rules one w/ time window (1) and one w/o time window (2) 2. Do not active rule (2) 3. Send an event that would potentially activate (2) 4. Unmarshall Session (i.e., simulate the recovery from a system failure) 5. Activate (2) 6.
