ipfix.getObs_domain_id() is declared as returning OvsDBSet<Integer> but actually returns OvsDBSet<BigInteger>

ipfix.getObs_domain_id() is declared as returning OvsDBSet<Integer> but actually returns OvsDBSet<BigInteger>

This causes a runtime ClassCast exception.

Here are some code snippets:

final OvsDBSet<UUID> ipfixSet = bridge.getIpfix();
if (ipfixSet != null && ipfixSet.size() > 0)
{
final UUID ipfixUUID = ipfixSet.iterator().next();
final IPFIX ipfix = (IPFIX) ovsdbConfigService.getRow(ovsNode, IPFIX.NAME.getName(), ipfixUUID.toString());
if (ipfix != null)
{
final OvsDBSet<Integer> obsDomainIdSet = ipfix.getObs_domain_id();
if (obsDomainIdSet != null && obsDomainIdSet.size() > 0)
{
final Integer i = obsDomainIdSet.iterator().next();

That last line causes a classcast exception.
