Florent Guillaume commented on NXP-1991:
----------------------------------------
Due to the fact that we used a hack, a non-pool-managed connection is used by
Jena (because Jena needs to commit() on it), and it appears it is never closed
(and we cannot close it because the pool needs it). Because of this transient
Jena prepared statements are never freed, therefore a leak.
A fix is to pass Jena a normal pooled connection but wrap it in a wrapper that
ignores commit() and setAutoCommit().
