ADF: Minor PS3 - PS5 bug

I could not access the security tab on my Webcenter admin console and was getting a  error which was cause by:

Caused by: java.lang.NullPointerException
    at oracle.webcenter.security.common.WCGroup.(WCGroup.java:74)
    at oracle.webcenter.security.common.IdentityWrapper.getGroup(IdentityWrapper.java:183)
 
We have a mapping from JNDI role to Administrator and it had this under members of the app role:
<member>
  <class>weblogic.security.principal.WLSGroupImpl</class>  <name>Administrators</name>
</member>

Removed this and all is good again.
