Spring Hibernate MySQL Test doesn't roll back -

i have problem transactional tests using spring 3.0.5, hibernate 3 , mysql 5. in logs seems there's ok , transaction rolls back, got record inserted database. configuration this:

<bean id="hibernatedatasource" class="org.apache.commons.dbcp.basicdatasource" destroy-method="close">   <property name="driverclassname" value="com.mysql.jdbc.driver" />   <property name="url" value="jdbc:mysql://localhost:3306/blog" />   <property name="username" value="user" />   <property name="password" value="password" />   <property name="defaultautocommit" value="false" /> </bean>  <bean id="transactionmanager" class="org.springframework.orm.hibernate3.hibernatetransactionmanager">   <property name="sessionfactory" ref="hibernatesessionfactory" /> </bean> <tx:annotation-driven transaction-manager="transactionmanager" />  <bean id="hibernatesessionfactory" class="org.springframework.orm.hibernate3.annotation.annotationsessionfactorybean">   <property name="datasource" ref="hibernatedatasource" />   <property name="schemaupdate" value="true" />   <property name="hibernateproperties">     <props>                <prop key="hibernate.dialect">org.hibernate.dialect.mysql5innodbdialect</prop>       <prop key="hibernate.current_session_context_class">thread</prop>                <prop key="hibernate.show_sql">true</prop>       <prop key="hibernate.connection.autocommit">false</prop>     </props>   </property>   <property name="annotatedclasses">     <list>       <value>pl.jedenpies.blog.domain.uzytkownik</value>     </list>   </property> </bean>  <bean id="uzytkownikdao" class="pl.jedenpies.blog.db.hibernate.dao.hibernateuzytkownikdao">   <property name="sessionfactory" ref="hibernatesessionfactory" /> </bean> 

test class:

@runwith(springjunit4classrunner.class) @contextconfiguration(locations = {"classpath:beans.xml"}) @transactionconfiguration(defaultrollback = true) public class uzytkownikdaotest {      private uzytkownikdao uzytkownikdao;      @test     @beforetransaction       public void test1config() {         assert.notnull(uzytkownikdao, "uzytkownikdao nie moze byc null");     }      @test        @transactional     @rollback     public void test2create() {         uzytkownik u = new uzytkownik();         u.setemail("my4@uzytkownik.pl");         u.sethaslo("blablabla");         assert.istrue(!u.isidustawione());         u = uzytkownikdao.create(u);         assert.notnull(u, "uzytkownik nie moze byc null");         assert.istrue(u.isidustawione());     }      @resource        public void setuzytkownikdao(uzytkownikdao uzytkownikdao) {         this.uzytkownikdao = uzytkownikdao;     } } 

log:

yes, googled lot problem didn't find solution. have no idea what's wrong.
