Way to get HA dedicated failover hosts via java SDK

Hi,

I'm using java VMware vSphere SDK 5.0.0  to get properties of managed object.

I set two hosts as dedicated failover hosts for HA admission control policy. I wanna this failover host list from SDK APIs. So I write following code to get:

======================================================================================================================

String[] properties = new String[] {"configuration.dasConfig.admissionControlPolicy.failoverHosts"};

PropertySpecExt pSpec = new PropertySpecExt();

pSpec.setType(moRef.getType());

pSpec.setPathSet(properties);

ObjectSpec oSpec = new ObjectSpec();

oSpec.setObj(moRef);

PropertyFilterSpecExt pfSpec = new PropertyFilterSpecExt();

pfSpec.setPropSet(new PropertySpec[] {pSpec});

pfSpec.setObjectSet(new ObjectSpec[] {oSpec});

List<PropertyFilterSpec> pfSpecList = new ArrayList<PropertyFilterSpec>();

pfSpecList.add(pfSpec);

List<ObjectContent> ocs = vimPort.retrieveProperties(getMOR(),pfSpecList);

======================================================================================================================

But I got exception info:

======================================================================================================================

Not sure if this exception is due to the property name "configuration.dasConfig.admissionControlPolicy.failoverHosts", so I tried "configuration.dasConfig.admissionControlPolicy". I managed to get the object of ClusterDasAdmissionControlPolicy, but it was found out that there was no any method/function to access failoverHosts (it is protected).

Does anybody have idea about this?
