Ldaptive exception reports queried attributes as array pointer

Error querying ldap server id: ldap, searchDn: ou=People,dc=ad,dc=example,dc=edu, filter: '(eduType=*)', returning attributes: [Ljava.lang.String;@4280974a

The rethrown exception from LdaptiveSessionImpl.list() outputs the attribute string[] as a string, rather than joining the elements with a delimiter.

catch (RuntimeException re) {

      GrouperUtil.injectInException(re, "Error querying ldap server id: " + ldapServerId + ", searchDn: " + searchDn

          + ", filter: '" + filter + "', returning attributes: " + attributeNames);
