I found a scenario where extra queries were being generated while cascading a persist to a new Entity. See the following example:
public class CascadePersistEntity implements Serializable
and the following scenario:
CascadePersistEntity cpe1 = new CascadePersistEntity(1);
CascadePersistEntity cpe2 = new CascadePersistEntity(2);
This results in two inserts and one select. The extra select is what I'm going to get rid of with this JIRA.
