How to access vSphere API method CreateVvolDatastore

I am attempting to access vSphere API method CreateVvolDatastore in list of Managed Object "HostDatastoreSystem" methods.

New CreateVvolDatastore method should be available in HostDatastoreSystem since vSphere API 6.0:

http://pubs.vmware.com/vsphere-60/index.jsp?topic=%2Fcom.vmware.wssdk.apiref.doc%2Fvim.host.DatastoreSystem.html

However method CreateVvolDatastore not showing up as an option. Note latest vijava pom.xml dependency entry is version 5.1:

              <dependency>

                     <groupId>com.vmware</groupId>

                     <artifactId>vijava</artifactId>

                     <version>5.1</version>

           </dependency>

Can anyone please advise how to successfully find / interface with vSphere 6.0 API class HostDatastoreSystem, method CreateVvolDatastore() ?

Is there any vijava SDK jar available containing this new method?

Thanks,

Elaine
