>         Environment: Hibernate 4.0.1.Final, any database, but tested locally with MySQL 5.1.58
>            Reporter: Tomas Salfischberger
>            Priority: Critical

> In org.hibernate.service.jdbc.connections.spi.AbstractMultiTenantConnectionProvider the call to releaseConnection(String tenantIdentifier, Connection connection) does not actually close the connection. The method was probably copied from getConnection(String tenantIdentifier) resulting in this code:
> {code}@Override
> public void releaseConnection(String tenantIdentifier, Connection connection) throws SQLException {
> 	selectConnectionProvider( tenantIdentifier ).getConnection();
> }{code}
> Which opens a new connection anytime a connection is supposed to be closed and thus quickly exhausts all available connections.
