Can't delete QOS from java api

I make the call to deleteRow() and I get a success value back but the qos isn't deleted.

If the qos is referenced from a port, that reference is removed so the port no longer has a reference to the qos but the qos itself still remains.

If the qos is not referenced from a port, it still remains.

Here is the code:

final Status status = ovsdbConfigService.deleteRow(ovsNode, Qos.NAME.getName(), qosUUID);
if (!status.isSuccess())
{
log.error("{}: {}", status.getCode(), status.getDescription());
log.error("Failed to delete Qos {} in {}", qosUUID, ovsNode);
}
else
{
log.debug("deleted Qos {}", qosUUID);
}
