ok I found an answer!!!
I had to add ec.dispose();
to the finally section of Kieran's ERJRFetchSpecificationReportTask _call method.
I will ask if there is a reason that this is needed. It must have something to do with the to_many relationship.
oh well, I seem to recall when I listened to the JasperReports podcast, someone was asking about the dispose() method being called. That's what led me to try it.
