Godmar Back commented on JBRULES-1459:
--------------------------------------

I believe this was when I had used the wrong MVEL version (1.2.something beta16)

>             Project: JBoss Drools
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>    Affects Versions: 4.0.4
>            Reporter: Godmar Back
>         Assigned To: Edson Tirelli

> The following test:
> package test;
> import java.util.Collections;
> import java.util.Map;
> import java.util.HashMap;
> dialect "mvel"
> rule "Rule #1"
> when
> then
>     m = new HashMap();
>     m.put("content", "hello ;=");
>     insert(m);
> end
> rule "Rule #2"
> when
>     s : Map (this["content"] matches "hello ;=")
> then
>     System.out.println("found it " + s);
> end
> ----
> produces:
> Exception in thread "main" org.drools.rule.InvalidRulePackage: Unable to determine the used declarations.
> Failed to compile:
> [Error: unterminated literal]
> [Near: "' "hell'"] : [Rule name=Rule #2, agendaGroup=MAIN, salience=0, no-loop=false]
>         at org.drools.rule.Package.checkValidity(Package.java:424)
>         at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:384)
> ....
> but this test works:
> package test;
> import java.util.Collections;
> import java.util.Map;
> import java.util.HashMap;
> dialect "mvel"
> rule "Rule #1"
> when
> then
>     m = new HashMap();
>     m.put("content", "hello ;=");
>     insert(m);
> end
> rule "Rule #2"
> when
>     s : Map (this["content"] matches "hello ..")
> then
>     System.out.println("found it " + s);
> end
> (The only difference between the two is that the right-hand side of "matches" was changed from "hello ;=" to "hello ..")
