Can you please provide an example how you construct a crit which fails ?

Please file a jira issue at
https://issues.apache.org/jira/browse/TORQUE/
As a workaround, you can try
crit.addSelectColumn(new org.apache.torque.util.functions.Count
("*"));
int count = SomePeer.doSelectSingleRecord(crit, new
org.apache.torque.om.mapper.IntegerMapper());
instead of
summary.addAggregate( "count", new Count( DogPeer.DOG_ID ) );
List<ListOrderedMapCI> results = summary.summarize( crit );
