java.lang.Objectorg.hibernate.connection.C3P0ConnectionProvider
public class C3P0ConnectionProvider
A connection provider that uses a C3P0 connection pool. Hibernate will use this by default if the hibernate.c3p0.* properties are set.

org.hibernate.cfg.Environment.RELEASE_CONNECTIONS
to aggressively release JDBC connections. However, the configured ConnectionProvider
must support re-acquisition of the same underlying connection for that semantic to work.
Typically, this is only true in managed environments where a container
tracks connections by transaction or thread.
Note that JTA semantic depends on the fact that the underlying connection provider does
support aggressive release.
