Edson Tirelli resolved JBRULES-2511.
------------------------------------

    Fix Version/s: 5.1.0.CR1
       Resolution: Out of Date


I tried your test cases with trunk and they work as expected. I tried with M2 and they failed. So it seems the problem is fixed already.

I am closing the ticket, but if you still find any problem with trunk as of revision #33510 or later, plz re-open the ticket and let me know.

Thanks for providing a good test case. Makes our investigation a lot easier and quicker.

> I've got a system that receives transactions. I want to implement the following rules:
> - raise an alarm(alarm event) when there aren't any transaction for an hour (or more);
> - if there's an alarm, no more alarms should be raised;
> - if there's an alarm and the system receives a transaction, that alarm should be retracted and the system should send an recovery event.
> I've implemented the rules this way:
> - ***start*** rule to insert an "EngineStart" event when the rules engine starts
> - ***notrx_after_start*** rule to detect absence of transactions during the first hour
> - ***notrx_after_trx*** rule to detect absence of transactions (during one hour) after last transaction
> - ***rearm*** rule to detect transactions and rearm the system.
> I made a Maven project with junits, which inserts transactions at specific time, in order to raise the desired events.
> Two set of tests were made:
> - the rules defined in "default" entry-point: the correspondent junit gives a NullPointerException in DefaultAgenda
> - the rules defined in "incoming" entry-point: the correspondent junit doesn't activate the ***rearm*** rule
