             Summary: Drools throws CCE when using global SessionClock in temporal operator
                 Key: DROOLS-993
                 URL: https://issues.jboss.org/browse/DROOLS-993
             Project: Drools
          Issue Type: Bug
          Components: core engine
    Affects Versions: 6.3.0.Final
         Environment: Max OS X 10.11.1, Oracle Hotspot 1.8.0_45
            Reporter: Duncan Doyle
            Assignee: Mario Fusco


When I insert the PseudoClock as a global in my KieSession, and I use the clock in combination with a temporal operator in a rule, I get the following CCE:

{code}
Caused by: java.lang.ClassCastException: java.lang.Long cannot be cast to java.util.Date
	at org.drools.core.base.evaluators.BeforeEvaluatorDefinition$BeforeEvaluator.evaluate(BeforeEvaluatorDefinition.java:301)
	at org.drools.core.base.EvaluatorWrapper.evaluate(EvaluatorWrapper.java:94)
	... 61 more
{code}

The interesting thing is that this line works:
{code}
$s: SimpleEvent(clock.currentTime after[300s] timestamp)
{code}

while this one fails:
{code}
$s: SimpleEvent(timestamp before[300s] clock.currentTime)
{code}

Reproducer can be found here: https://github.com/DuncanDoyle/drools-cce-issue
Just run 'mvn clean test'.
