CLONE - NetworkTopology::getLeaf should check for invalid topologies
--------------------------------------------------------------------
Key: NET-453
URL: https://issues.apache.org/jira/browse/NET-453
Project: Commons Net
Issue Type: Bug
Affects Versions: 1.0
Reporter: Colin Patrick McCabe
Fix For: 1.0
Attachments: HDFS-3073.002.patch
Currently, NetworkTopology::getLeaf doesn't do too much validation on the
NetworkTopology object itself. This results in us getting ClassCastException
sometimes when the topology is invalid. We should have a less confusing
exception message for this case.
