Atomic Integer missing when deploying Grails 1.3.4 application to Geronimo 2.2

[Scott Ryan]

I am trying to deploy a grails 1.3.4 application to geronimo 2.2 and have used 
the following geronimo-web.xml file in my application.  

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://geronimo.apache.org/xml/ns/j2ee/web-1.1";>
    <environment xmlns="http://geronimo.apache.org/xml/ns/deployment-1.1";>
        <moduleId>
            <groupId>com.triplecreekassociates</groupId>
            <artifactId>OM5</artifactId>
            <version>5.0.0-RC1</version>
            <type>war</type>
        </moduleId>
        <hidden-classes>
            <filter>org.springframework</filter>
            <filter>org.apache.cxf</filter>
            <filter>org.apache.commons</filter>
        </hidden-classes>        
    </environment>
    <context-root>/om5</context-root>
</web-app>

There is a lot of conflicting information on how to do this deployment but when 
I run with this configuration from the IBM developer site website I get the 
following error:

Do I have a mismatch in the server I am trying to use since groovy has been 
upgraded in grails recently?
