When profiling, has a full GC & weak reference collection happened
before you count "live instance"?
Probably those "live" instances are only weakly reachable and will be
cleaned up later.
(The driver uses weak references + a reference queue that is polled
before each query execution to clean up server-side allocated
resources corresponding to JDBC statements / resultsets that were not
properly closed, just discarded)

If that's not the problem, I'd need to know the path from a GC root to
the live instances.
