Notwithstanding the OP's issue . is there any sensible way of preventing
this? Ie. how to detect connections are being returned to the pool without
them properly ending transactions?
Is it even possible?

Ok. Understood. So, each time a new thread that uses SqlMapClientImpl is
spawned, a Connection object is removed
As I understand it, SqlMapClientImpl (SqlMapClient) hides or wraps the primary
JDBC object, Connection. So, we can essentially do everything with
SqlMapClient that we can with JDBC's Connection object (including starting,
commiting or aborting transactions). However, with iBatis, we don't have
