In the accounts payload, the namespace prefix for the accounts_common element is sometimes ns2, and sometimes ns3. This can change whenever tomcat is restarted. It seems like this can happen whenever there is more than one namespace declaration on an element. The roles payload doesn't have this problem, because the jaxb namespace isn't declared there, as it is on accounts_common. Can it be removed from accounts_common? It's never used. Otherwise, a similar fix as is fine.
accounts-common-list has the same issue.
