Fix for "HibernateJpaDialect - JDBC Connection to reset not identical to originally prepared Connection" warning

After updating an application to Hibernate 5.1.1 from 5.1.0, I started seeing the following warning:

HibernateJpaDialect - JDBC Connection to reset not identical to originally prepared Connection

I did not find an "explicit" solution on the Internet, but looking through some of the code fixes in the ngrinder project, I figured out that I could fix my problem the same way by adding <prop key="hibernate.connection.release_mode">on_close</prop> to applicationContext.xml:

	<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
	<property name="dataSource" ref="dataSource"/>
	<property name="persistenceUnitName" value="pu"/>
	<property name="packagesToScan">
	<list>
	<value>com.appia.model.beans</value>
	</list>
	</property>
	<property name="jpaVendorAdapter">
	<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
	<property name="showSql" value="${orm.show_sql}"/>
	<property name="databasePlatform" value="com.appia.pss.util.PostgresDialect"/>
	</bean>
	</property>
	<property name="jpaProperties">
	<props>
	<prop key="hibernate.format_sql">${orm.format_sql}</prop>
	<prop key="hibernate.connection.release_mode">on_close</prop>
	</props>
	</property>
	</bean>

Thanks for this solution, JunHo!
