spring eclipselink problem with IntegrityException

I try to use spring with eclipseLink and I've got an IntegrityException. This is my configuration:

<?xml version="1.0" encoding="UTF-8"?>

    </property>
</bean>

<bean id="jpaTemplate" class="org.springframework.orm.jpa.JpaTemplate">

</bean>

and exactly exception is:

but i don't have this problem when I use another Vendor

org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter

any ideas?

Try to use this loadtimeweaver implementation:

package net.palesz.util;

import org.springframework.instrument.classloading.SimpleLoadTimeWeaver;

public class JpaAwareLoadTimeWeaver extends SimpleLoadTimeWeaver {
    @Override
    public ClassLoader getInstrumentableClassLoader() {
        ClassLoader instrumentableClassLoader = super.getInstrumentableClassLoader();
        if (instrumentableClassLoader.getClass().getName().endsWith("SimpleInstrumentableClassLoader")) {
            return instrumentableClassLoader.getParent();
        } else {
            return instrumentableClassLoader;
        }
    }
}

Spring context.xml config:

<bean id="loadTimeWeaver" class="net.palesz.util.JpaAwareLoadTimeWeaver" />

An odd error because IndirectSet is valid. It seems to be a class loader issue, but I have not seen this in Spring before.

It could be related to your usage of loadTimeWeaver, so you could try removing that.

In what environment are you running Spring?

you have to use agent for dynamic weaving
-javaagent:spring-agent-2.5.6.jar
i had tried eclipseLink agent, but it didn't work.

more info about weaving for JPA on Spring:
http://docs.spring.io/spring/docs/3.0.0.M3/reference/html/ch14s06.html
if you would like run your code on tomcat:
