org.jclouds.openstack.keystone.v2_0.domain.User.getTenantId() method does not return valid tenant id for user

jclouds.wire prints tenant id associated with that user, but when I iterate users list and print them individually, it is missing.

Tenant

{id=180ff309a56f489d9746c1c12670c10b, name=admin, description=admin Tenant, enabled=true}

User

{id=43a124f9f4b44f978e23989936480c16, name=newUser, email=new.email@example.com, enabled=true, roles=[]}

From the above log statements, one can see that the tenant id (22d34e93b3d54753b99ec5f6052ba578) is printed inside jclouds.wire and is missing in the second line.
