Retracting events using PseudoClockScheduler causes ClassCastException
----------------------------------------------------------------------

                 Key: JBRULES-2299
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2299
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core, drools-core (fusion)
    Affects Versions: 5.1.0.M1
            Reporter: Maciej Prochniak
            Assignee: Mark Proctor


When job is scheduled e.g. in sth like not A(this after [1s,10s] $a)
and relevant event is retracted from working memory, the job should be removed. 
However, PseudoClockScheduler usues queue containing wrappers for job (ScheduledJob), 
and remove method tries to remove job without this wrapper which causes:

java.lang.ClassCastException: org.drools.common.Scheduler$DuractionJob incompatible with org.drools.time.impl.PseudoClockScheduler$ScheduledJob

Solution would be probably to wrap job which should be removed
