found a similar error message here: https://stackoverflow.com/questions/22481540/hibernate-exception-javassist-0-cannot-be-cast-to-javassist-util-proxy-proxy

this could be due to a version conflict with the javaassist.jar

Please check your dependency tree to see which version gets resolved. Maven Command:

mvn dependency:tree

ZK needs at least version 3.18.2-GA
