Hi, I am a DROOLS newbie. I apologize if this has been asked before. This rule (R1) is not syntactically correct in the Eclipse .DRL view. 

rule "R1" 
    when  
        Message( 
             ((attrA = "foo" && _attrB == "bar") || AttrA== "foo")  //syntax error (curious, why?)
        )
    then 
        System.out.println( "R1 pattern-matched Message.  DROOLS Consequence executing now." );    
end
but R2 is syntactically correct = 

rule "R2" 
    when  
        Message( attrA = "foo" && _attrB == "bar") || 
        Message (AttrA== "foo")

    then 
        System.out.println( "R2 pattern-matched Message.  DROOLS Consequence executing now." );    
end
In Drools 5.2, are R1 and R2 semantically equivalent?
