public static class HarvesterException.HarvestableTypesNotFoundException
HarvestableTypeNotFoundException occurs when a referenced harvestable type
is unknown to the Harvester. This exception is thrown when the missing
item is not required to be configured. For example see method
getHarvestableAttributes(String typeName) defined on the Harvester runtime
MBean. Note that this exception does necessarily mean that the typename
is bad, only that it is currently not known.
