<br> Yes, I see. Can you please manually update your local mvel jar to version 2.0.6 (latest) and try again? I am talking to the MVEL author to make sure the problem is fixed in the latest version, but of course, if you can confirm this on your side, it would be best.<br>

<br>
I'm using maven to manage my libraries, thus I add these line in my pom.xml:<br>
<dependency><br>
<groupId>org.drools</groupId><br>
<artifactId>drools-api</artifactId><br>
<version>5.0.0.M4</version><br>
</dependency><br>
<dependency><br>
<groupId>org.drools</groupId><br>
<artifactId>drools-core</artifactId><br>
<version>5.0.0.M4</version><br>
</dependency><br>
<br>
And I can see that mvel2-2.0.4 has been added, besides drools-api and core<br>
5.0.0.M4<br>
Thanks for the reply<br>
