---------------------------------------

Philipp, I could not reproduce this issue in 5.6, could you submit a full test case?
Thanks

>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>    Affects Versions: 5.5.0.Final

> 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. Exception
> java.lang.NullPointerException
