Regression: parser rebuts multiple bindings in constraint conjunction and disjunction
-------------------------------------------------------------------------------------

                 Key: JBRULES-3025
                 URL: https://issues.jboss.org/browse/JBRULES-3025
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-compiler (expert)
    Affects Versions: 5.2.0.M2
            Reporter: Wolfgang Laun
            Assignee: Mark Proctor
            Priority: Blocker
             Fix For: 5.2.0.CR1


The DRL given below compiled in 5.1.1 and executed as expected, i.e., both rules fired, producing 
   or R=1x2
   and R=1x2

Now, a syntax error is flagged at the position of the 2nd binding ($w:). Moreover, the DRL parser is thrown off-track and crashes with sn EmptyStackException as soon as more rules follow.

package binding;

declare Rect
  length : int
  width : int
end

rule insert
salience 100
when
then
   Rect r = new Rect();
   r.setLength( 1 );
   r.setWidth( 2 );
   insert( r );
end

rule "binding and"
when
    $r: Rect( $l: length == 1 && $w: width == 2 )
then
    System.out.println( "and R=" + $l + "x" + $w );
end

rule "binding or"
when
    $r: Rect( $l: length == 1 || $w: width == 1 )
then
    System.out.println( "or R=" + $l + "x" + $w );
end
