Correct destroy of producer method.

[tonywestonuk]

I have an @ApplicationScoped class containing a producer method....below.

When I start/stop the application with the manager app, I get the error:
javax.management.InstanceAlreadyExistsException:
tomcat.jdbc:name="org.tony.DBIProducer/dataSource",context=/tribune_etl,engine=Catalina,type=ConnectionPool,host=localhost,class=org.apache.tomcat.jdbc.pool.DataSource


What do I need to do, to avoid this error. 
Thanks.



@ApplicationScoped
public class DBIProducer implements ConnectionFactory {
        
        @Resource
        DataSource dataSource;
        
        @Resource(name="db_schema")
        String schema;
        
        @Produces 
        public DBI createDBI(){
                DBI dbi = new DBI(this);        
                
                return new DBI(this);
        }

        
        @Override
        public Connection openConnection() throws SQLException {
                Connection connection = dataSource.getConnection();
                connection.setSchema(schema);
                connection.setAutoCommit(true);
                return connection;
        }
}
