How to disable caching in OpenJPA 2.0.1 (change: problems with BoneCP)

Question

I cannot disable caching in OpenJPA 2.0.1.

I set the following properties in my persistence.xml:

<property name="openjpa.DataCache" value="false"/>
<property name="openjpa.QueryCache" value="false"/>
<property name="openjpa.jdbc.QuerySQLCache" value="false"/> <!-- I don't believe this is  necessary -->

And I see that the correct values ​​for these properties exit the system when my application starts.

I created a base object to verify this using the main method, which simply queries the table every second. I create a new EntityManager at each iteration. When I run it against an empty TEST table, and then manually insert the data into the test:

insert into TEST values (1,'a');

it never picks up new data (although if I re-run the program, it does).

import java.util.List;    
import javax.persistence.*;

@Entity
@Access(AccessType.PROPERTY)
@Table(name="TEST")
public class Test {

    private int id;
    private String name;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Column(name="ID")
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }

    @Column(name="NAME")
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    // SIMPLE TEST CASE
    public static void main(String[] args) throws Exception {
        EntityManagerFactory factory = Persistence.createEntityManagerFactory("su3", null);
        while(true) {
            EntityManager em = factory.createEntityManager();
            TypedQuery<Test> q = em.createQuery("select t from Test t", Test.class);
            List<Test> res = q.getResultList();
            for (Test t :res) {
                System.out.println(t.getId()+", " + t.getName());
            }
            Thread.sleep(1000);
            em.close();
        }
    }
}

what am I doing wrong?

, c3p0 :

<property name="openjpa.ConnectionDriverName"  value="com.mchange.v2.c3p0.ComboPooledDataSource"/>
<property name="openjpa.ConnectionProperties" value="DriverClassName=com.mysql.jdbc.Driver,jdbcUrl=jdbc:mysql://localhost:3306/dbname,characterEncoding=UTF8,useUnicode=true,user=username,password=password,autocommit=false,automaticTestTable=testtable,idleConnectionTestPeriod=60"/>
<property name="openjpa.DataCache" value="false"/>
