If this is the case, there is a way to make CruiseControl start ant as an external process, I think using a script attribute on the ant builder. Try this, it might help. Also, there might be an underlying bug, either in CruiseControl or in Ant. Opening a ticket either in CruiseControl's JIRA or in ant's bugzilla depending on which application you think is misbehaving might help. If CruiseControl is starting ant within the CruiseControl process, I would say it is primarily a CruiseControl bug.
