regression: set test operator "in" broken 
------------------------------------------

                 Key: JBRULES-3114
                 URL: https://issues.jboss.org/browse/JBRULES-3114
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-compiler (expert)
    Affects Versions: 5.2.0.Final
            Reporter: Wolfgang Laun
            Assignee: Mark Proctor
            Priority: Blocker
             Fix For: FUTURE


This simple DRL runs into a NPE

rule a
when
then
    insert( Integer.class );
end

rule xxx
when
    $t: Class( $name: name not in ( "java.lang.Integer", "Bar", "Blech" ) )
then
    System.out.println( "odd name: " + $t.getName() );
end

Caused by: java.lang.NullPointerException
	at org.drools.base.mvel.MVELPredicateExpression.evaluate(MVELPredicateExpression.java:104)
	at org.drools.rule.PredicateConstraint.isAllowed(PredicateConstraint.java:291)

If the "not" is removed, another strange error is thrown, claiming that 'name' cannot be accessed.
