java.lang.NoClassDefFoundError: com/google/common/collect/MapMakerInternalMap$Strength when running custom pyton script with jython-eap6

Issue

• We have a same Jython script that’s executed on two different redaht release: redhat 6.5 and redhat 6.6
  On ReadHat 6.5 the script is working fine.

The only difference we see between the two servers is the version of the Jython package.
On RedHat 6.5 it’s jython-eap6-2.5.2-5.redhat_2.ep6.el6.4.noarch
On Redhat 6.6 it’s jython-eap6-2.5.2-6.redhat_3.1.ep6.el6.noarch

On version 6.6 it gives us the following error:

java -classpath /opt/app/jboss/bin/client/jboss-cli-client.jar:/usr/share/java/jython-eap6/jython-standalone.jar org.python.util.jython
