Error in JCloud KeystoneApi getRoleAdminApi

[Alka Beniwal]

Hi,

I am developing a code to retrieve list of roles in OpenStack.

*Code-*
 RoleAdminApi roleAdminApi=  keystoneApi.getRoleAdminApi().get();//error
        FluentIterable<? extends Role> list1 = roleAdminApi.list();

*Error-*
java.lang.IllegalStateException: Optional.get() cannot be called on an
absent value


Any help is appreciated.
