vaadin NPE on User Profile

[allen_joslin]

I'm in the process of integrating the latest alfresco [201605-linux-64] & activiti [5.22.0] community versions on the same CentOS 7 server against a FreeIPA 3.0.0 [openldap] server.  I've finally got my ldap settings straightened out, and turned off tomcat serialization – but I get an NPE when bringing up any UserProfile dialogs that show the user picture.  There are also NPE's when trying to upload a picture.  But our LDAP server doesn't support user Pictures.

<bean class="org.activiti.ldap.LDAPConfigurator">
  <!– Server connection params –>
  <property name="server" value="ldap://ipa.our-domain.com" />
  <property name="port" value="389" />
  <property name="user" value="uid=anonymous,cn=users,cn=accounts,dc=our-domain,dc=com" />
  <property name="password" value="our-secret" />
  <!– Query params –>
  <property name="baseDn" value="dc=our-domain,dc=com" />
  <property name="queryUserByUserId" value="(&amp;(objectClass=inetOrgPerson)(uid={0}))" />
  <property name="queryUserByFullNameLike" value="(&amp;(objectClass=inetOrgPerson)(|({0}=*{1}*)({2}={3})))" />
  <property name="queryGroupsForUser" value="(&amp;(cn=*)(memberUid={0}))" />
  <!– Attribute config –>
  <property name="userIdAttribute" value="uid" />
  <property name="userFirstNameAttribute" value="givenName" />
  <property name="userLastNameAttribute" value="sn" />
  <property name="userEmailAttribute" value="mail" />
  <property name="groupIdAttribute" value="gidNumber" />
  <property name="groupNameAttribute" value="cn" />
