Java 1.5 JPA with Hibernate and H2 is slow to create the EntityManagerFactory -

i'm trying test of our db layer in junit.

the problem have persistence.createentitymanagerfactory() takes > 200 seconds! googling h2, jpa, hibernate in combination createentitymanagerfactory gives nothing useful.

this test:

import static org.junit.assert.asserttrue;  import java.util.date;  import javax.persistence.entitymanager; import javax.persistence.entitymanagerfactory; import javax.persistence.persistence;  import org.junit.test;  public class minimalset {     @test     public void testnamedquery() {         date starttime = new date();          entitymanagerfactory entitymanagerfactory = persistence.createentitymanagerfactory("testpersistence");         entitymanager entitymanager = entitymanagerfactory.createentitymanager();          date endtime = new date();          // did take less 10 seconds?         asserttrue(((endtime.gettime() - starttime.gettime()) / 1000.0) < 10.0);     } } 

this persistence.xml:

<?xml version="1.0" encoding="utf-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">     <persistence-unit name="testpersistence" transaction-type="resource_local">         <provider>org.hibernate.ejb.hibernatepersistence</provider>         <properties>             <property name="hibernate.show_sql" value="true" />             <property name="hibernate.dialect" value="org.hibernate.dialect.h2dialect" />             <property name="hibernate.connection.url" value="jdbc:h2:mem:test" />             <property name="hibernate.connection.driver_class" value="org.h2.driver" />             <property name="hibernate.connection.username" value="root" />             <property name="hibernate.connection.password" value="" />             <property name="hibernate.show_sql" value="true" />             <property name="hibernate.format_sql" value="false" />         </properties>     </persistence-unit> </persistence> 

i don't use other config file (e.g. hibernate.cfg.xml).

i'd appreciate clue why takes long.

thanks.

update:

it has started running fast (<2 seconds). i'm thinking there event waiting for. of talk network?
